Why can t you drink seawater, but you can drink very salty soup?

I think there are three explanations for what the "can't" in the so-called "can't drink" in "can't drink seawater":

The first explanation is that seawater is an unhealthy thing, and it is not good for people's health after eating, just like someone saying that raw water cannot be drunk, which is also what it means, drinking it will not make people die, but it will make people sick. This statement is correct, because the sea water is full of microorganisms, parasites and other marine life corpses, so drinking the sea water without treatment is definitely not good for the body, and people with stronger resistance can say that they should almost vomit and diarrhea.

The second explanation is that seawater is a bad thing, and drinking it will make people feel uncomfortable from the taste. This is true, because seawater contains heavy metal particles such as magnesium ions, it is bitter to drink, and because it is so salty, for most people, probably no one wants to think of seawater as a good drink

The third explanation is that seawater cannot replace freshwater, especially if people do not drink seawater to quench their thirst without fresh water supplementation. This statement is also true, because the salinity of seawater is relatively high (the concentration of sodium chloride in seawater, that is, salt, is much higher than the osmotic pressure of plasma in the human body, so after drinking seawater, the cells in the human body will seep out the water in the saltwater environment, which makes people's dehydration more serious and accelerates death.

These three explanations are why seawater cannot be drunk from different perspectives, and the reason why very salty soups can be drunk is because very salty soups do not have these characteristics of seawater, but are just salty.

For example, the first explanation is that seawater is an unhealthy thing, so you can't drink it, but very salty soup is not, except for people with high blood pressure who may be cautious, people don't have to worry about parasites or bacteria in the soup, and they don't have to worry about diarrhea and vomiting if they drink it (of course, spoiled soup is not included).

Another example is the second explanation, seawater is a bad thing, so you can't drink it, but the very salty soup is just salty, the soup itself is not bitter, and some people are willing to drink very salty soup.

Finally, the third explanation is that seawater is not a substitute for fresh water, and people cannot drink seawater to quench their thirst when they are dying of thirst. I don't think this happens when you drink soup, do you? If you really encounter it, then very salty soup is not drinkable, but in our ordinary life, there is no such assumption at all, so very salty soup can be drunk in this sense.

So, the question is vague and doesn't make much sense, but I'm really an idle person who can write so many words on this question. Helpless

Seawater can't be drunk because in addition to salt, there are a lot of messy impurities in seawater, obviously these impurities will seriously harm people's bodies, not to mention the salt content in seawater is very high, I have entered seawater in my mouth several times, it is too salty, like salt brine, unless you are born as a fish, seawater must not drink. Very salty soup, first of all, in addition to salt, the soup is mainly clean water, and there are very few impurities in the normal tap water, not to mention that now our family also uses a water purifier to purify the water again, plus high temperature boiling, of course, you can drink. However, from a health point of view, the soup should not be too salty, which is easy to cause people to suffer from high blood pressure.

Glad for your question.

First of all, thank you.

The sea is salty, it's not just salt... Microorganisms, heavy metals, bacteria, salts... A whole bunch.

The presence of salt makes the saltiness of the sea water surpass the salty soup we usually drink casually. Drinking it like this will not quench your thirst at all, and it will also increase the osmotic pressure on the outside of the cells, which you can understand as saltiness. At this time, for balance, it is the water inside the cell that flows outward.

Not only will it not quench your thirst, but it will make you thirsty! And in severe cases, it can lead to shock and even death.

Even if the immunity of a young adult cannot resist the impact of bacteria and microorganisms on the body brought by drinking a lot of seawater, we usually advocate washing hands before eating, wearing masks in crowded places, etc., all in order to minimize contact with bacteria and pathogens. Drinking seawater is directly sent into the body in large quantities.

Can't you drink it?! Salt not only causes obesity and high blood pressure, but also increases your chance of getting various cancers, okay?! And it's not even a little bit better.

And very terrible diabetics, recent studies have found that it is also related to eating salt, yes, you read that right, heavy taste can easily induce diabetes.

If mine is helpful to you, I hope you can give me a thumbs up! It doesn't cost much traffic! Believe me! Hey, hey, hey!

Seawater is not exactly the same as the water we usually drink. If we put seawater and fresh water in two pots, and then heat them to evaporate and dry, you will find that there is almost no solid material left in the pot containing fresh water, while there is a large white solid matter precipitate in the pot containing seawater. Why is this so?

It turns out that freshwater is composed of water and trace mineral elements, and in the process of heating and evaporating freshwater, the water is constantly vaporized, and finally the water is completely converted into water vapor and escapes. Therefore, there is basically no residue in the pot. But the seawater family is very complex, in 1 kilogram of seawater contains about 35 grams of salt, in addition to calcium sulfate, magnesium sulfate and a large number of substances, these substances have a high melting point and are not easy to volatile, in the process of heating seawater, water is constantly converted into water vapor, the concentration of seawater continues to increase, after the water is completely evaporated, these substances are deposited in the form of solid to the bottom of the pot.

Because salt is salty, calcium sulfate is astringent, and magnesium sulfate is bitter, the sea water becomes salty, astringent, and bitter, and can be drunk directly without trust.

Where do these substances in seawater come from? It turns out that the water of the rivers on land is constantly washing away the mud and rocks on both sides as it flows to the sea. The soluble minerals on land are dissolved by the water and carried into the sea by its continuous flow, so that the sea gradually becomes salty, bitter and astringent.

If you drink seawater, you can take a lot of fresh water to remedy it. Large amounts of fresh water can dilute the excessive intake of minerals and elements by the body, excreting them from the body through sweat.

And also. According to statistics, among those who died at sea, the mortality rate of those who drank seawater was 12 times higher than that of those who did not. Why is that?

It turns out that the human body has to excrete about 150 grams of water in order to excrete 100 grams of salts contained in seawater. Therefore, people who drink seawater not only cannot replenish the water that the human body needs, but also accelerate dehydration, and eventually cause death.

Seawater is drinkable after desalination. There are dozens of methods of seawater desalination, the most important ones are distillation, electroosmosis, freezing, membrane separation, etc. Distillation is the most widely used method nowadays, which is to heat and boil water to produce steam in seawater, and then condense the steam to become distilled water.

It is best to mix a small amount of (2) clean seawater or an appropriate amount of mineralizer into the fresh water prepared by distillation, so that the water tastes delicious, and also supplements the inorganic salts that are lacking in distilled water and necessary for the human body.

In special circumstances such as distress and life-saving at sea, in order to save fresh water, part of the seawater can be mixed with fresh water for drinking. Some people have done experiments that people drink a mixture of half seawater and half fresh water in a short period of time, and the rolling branch is generally harmless to the human body.

The main reason why seawater can not be drunk is that some substances in the water are not conducive to the digestion and absorption of our human body, which will lead to cold water can not be easily drunk, and some salt will be left after the seawater is boiled dry, and after these salts are refined, it becomes a kind of table salt that we usually use.

Just; Coarse salt. Seawater should not be easily used, and there should be no assurance that there will be some stains on the inside.

When seawater is boiled dry, it leaves behind salt and other toxic substances, so it is salty and cannot be used as drinking water, and drinking it can be harmful to the entire urethral system.

Why is seawater salty? That's because there's salt in the water. However, seawater is not salt water, most of the salt in seawater is really the salt we usually use for cooking, and the pure salt is called sodium chloride.

Most of the salt we eat comes from the seawater, and there are about 30 grams of sodium chloride in each liter of seawater, enough for our family of three to eat for two days. There are about 3 to 5 grams of other substances in a liter of seawater, but there are more than 80 of these substances, and this is only possible with current analytical methods. If you say that all the elements in nature are found in seawater, then you can't say that it is wrong, because there are so many substances in seawater, and it is too complicated.

Some substances are so small that our instruments can only know that they are present in seawater, but we really don't know how much of them. For example, gold is also found in seawater, but the content is very small, almost a standard.

After the quasi-50-meter swimming pool is filled with water and then thrown in a piece of fruit candy, can you say that the water in the pool is already sweet? There is only so much gold in seawater, and it takes a lot of technology and energy to extract it.

The proportion of various substances in the sea is quite constant, and marine life is very adapted. American lobsters will never make a fuss when they come to China. These substances in seawater are formed after billions of years of dissolution, erosion, and interaction, and these substances are not simply piled up in the water, these substances together with the seawater support all kinds of life in the sea, and marine life is also fully adapted to the seawater, and most of them cannot survive without the seawater.

Creatures living on land may never understand how fish in the sea are not afraid of saltiness, and they are bitter and astringent.

Seawater is the "hometown" of salt, and seawater contains various salts, of which about 90% of the cluster group is sodium chloride, which is also the salt that seeps into the blind. In addition, it also contains magnesium chloride, magnesium sulfate, magnesium carbonate and other salts containing potassium, iodine, sodium, bromine and other elements. Magnesium chloride is the main ingredient of the brine used for tofu, and the taste is bitter, so the seawater with a large proportion of salt is salty and bitter to drink.

If all the salt in the seawater is extracted and spread on the land, the height of the land can be increased by 153 meters; If all the water in the world's oceans were evaporated, a 60-meter-thick layer of salt would accumulate on the seabed.

Where does so much salt come from in the sea? Scientists compared seawater to river water, studied soil and gravel after rain, and learned that the salt in seawater is brought by rivers on land through flowing water. When the rainwater falls to the ground, it collects lower and forms small rivers, which flow into the rivers, and some of the water seeps into the ground through various formations, and then emerges in other areas, and finally flows into the sea.

As water flows, it passes through various soil and rock layers, causing it to decompose to produce various salts, which are carried into the sea with the water. As seawater evaporates over time, the concentration of salt increases, and it is not surprising that the oceans have been formed for hundreds of thousands of years, so it is not surprising that seawater contains so much salt.

There's a very small amount of fresh water on Earth, and most of it is seawater, and you can't quote it directly, because it tastes salty. Why is that?

The primeval ocean is not salt water, but fresh water, but due to the long-term erosion of rocks and salt mines in nature, the salt in it is brought to the ocean, and slowly accumulates more and more tired, and our sea water becomes the current sea water, but the salt we often eat is not the ocean, but the lake salt and well salt, which is because of the serious pollution of the ocean.

Why is seawater salty? Star Awareness Project

First of all, the earth's crust contains a large amount of sodium chloride, which is dissolved in water, and with the evaporation of seawater, sodium chloride remains in seawater, so seawater is salty. In addition to sodium chloride, there are many other substances in seawater, which cannot be absorbed by the human body.

Because there is salt in it, the sea water cannot be drunk, and the more you drink, the thirstier you become, just like you eat salt.

Seawater is salty because of its high salt content. It can be drunk, but salt water is a hypertonic liquid, and drinking too much can easily cause electrolyte imbalances.

Because seawater contains a large number of various salts, of which sodium chloride accounts for 90%, seawater is salty, generally undrinkable, and needs to be desalinated.

The reason why seawater is salty is because there are about 3 5% salt in seawater, most of which is sodium chloride, and a small amount of magnesium chloride, potassium sulfate, calcium carbonate, etc. It is these salts that make the sea water bitter and astringent, difficult to consume.

You can't drink it, the salty ones will only get thirstier the more you drink.

Seawater is rich in sodium chloride, so seawater is salty. You can't drink seawater, and the more you drink, the thirstier you get.

The salinity of seawater is four times higher than the salt content of the human body, and drinking seawater will increase the total osmotic pressure in the body, although it can quench thirst temporarily, but soon it will urinate a lot, causing a large loss of water in the body.

Every year, a large amount of water evaporates from the surface of the oceans, and some of this water is transported over the land through atmospheric movements, and then forms precipitation and falls to the ground. Can't drink it.
