Seawater is heated to obtain steam, which must be drawn out and cooled into liquid water before drinking.
The remaining salt in the pot should retain a part of the water, and the crystallized salt can be eaten, if it is all steamed dry, dust and dissolved substances such as magnesium sulfate will crystallize together, and mix with sodium chloride, making it inedible.
-
The steamed water vapor is theoretically drinkable after condensation, but due to the lack of minerals and other substances that are beneficial to the human body, distilled water is not suitable for long-term human drinking. For your question:
1. Water vapor can be condensed at room temperature, so a longer air condensate tube can be selected for condensation; As mentioned above, the steamed water excludes the pollution caused by the unclean container, and can be drunk, but it can be drunk for a long time;
2. Most of the salt in it is sodium chloride, that is, table salt, and the salt that comes out in this way is generally relatively coarse salt, and there are some impurities such as magnesium chloride and sodium sulfate.
-
Water vapor can't be drunk, just cool it into water.
1. You can use a condenser tube and you can drink.
2. Not only salt (sodium chloride) but also a small amount of magnesium chloride, sodium sulfate and other impurities. High School Chemistry, First Experiment: Sea Salt Purification, See for Yourself.

Oh, the one upstairs doesn't point to the question ( o Ah!
Now the simpler thing is to cover the pot directly with a cover (cold, wash it), heat it, the water on the cover is distilled water, people can drink it directly, it is non-toxic and harmless, and it will never be cancerous if you drink it!
However, drinking only this kind of water for a long time will lead to a lack of trace elements in the body (long-term does not refer to 1 day and 2 days, but refers to 1 year and 2 years).
Some of the salt in the pot is the crystallization of calcium and magnesium compounds, some are salt, miscellaneous, all mixed together, most of them are salt, generally speaking, it is impossible to distinguish (you go to play with chemical reactions, all mixed together, either there is no reaction, or all reactions), if you want to distinguish, you have to use a robot puppet!
-
The water vapor cannot be drunk, and the salt obtained is coarse salt, which is easily damp into lumps
-
Of course, it is the same substance, and it is the same thing that water has changed from liquid to gaseous, and it is the same reason that water freezes, water becomes ice, in fact, it is still water, but the form has changed, it will become water after heating, and water vapor will also become water after condensation.
-
It's the same substance, but in a different physical form!
-
It is the same substance, but the heat energy carried by the steam is large.

Boiling water is not distilled water.
The water boiled at home is not distilled water, often we boil the water at a temperature of about 100 through the kettle or other containers called boiled water, which contains a lot of minerals and insoluble substances, which can supplement the trace elements required by the human body.
Distilled water generally refers to the water that is pure after special treatment and does not contain any impurities and bacteria, which is usually used more in chemical laboratories and can be processed and manufactured by distillation, ion exchanger or other methods, which is the raw water in the true sense.
Strictly speaking, boiled water is called boiled water, which contains minerals and insoluble substances, while distilled water is pure water that has undergone special treatment and does not contain impurities, which is widely used in chemical laboratories, the former can be drunk for a long time, and the latter is not suitable for long-term drinking.
How to make distilled water:
Ingredients: Deep pot, curved lid, ice cubes.
Steps: 1. First add water to the pot and then heat it well over medium-high heat. At this time, we put the large bowl into the pot and let the large bowl float on the water surface (this function is used to receive distilled water).
We need to pay attention to the process of receiving distilled water at all times to avoid receiving too much water and letting the bowl fall. Next, we need to flip the lid over so that the lid is on top of the pot.
2. Then, we are going to send ice cubes to the field, this is mainly to put ice cubes on the lid of the pot. The amount of ice cubes in this depends on the size of our lid. It is important to note here that since the ice cubes dissolve quickly when heated, it is recommended that we pour out the water and add the ice cubes again (the purpose of this type of ice cubes is to continuously speed up the cooling of the steam in the pot, so that the steam can drip into the large bowl).
3. After doing the above links, we can achieve initial results, this hand only needs to lift the lid slightly, and you can immediately see the steam will gradually condense on the lid to form small water droplets dripping into the bowl.

Introduction: We hear distilled water.
This name is not unfamiliar with wild grinding, distilled water is made of some water after boiling, due to evaporation and condensation. But in everyday life, can you boil distilled water and drink it? What does it do? Let's find out.
<> fact, distilled water is the water that evaporates from some raw water, and the harmful substances in it have classification and benzene compounds, and there may be mercury when evaporating. Distilled water provided to people on the market does not have so many harmful substances, but it contains some trace elements.
There are all of them, so they can't provide some trace elements that the human body needs. Although distilled water is drinkable, it is not as good as our ordinary pure water and drinking water, because the water we drink regularly, it may have some minerals, which is very good for the human body. Although distilled water is drinkable and non-toxic, it is not recommended to drink it often, and there will be some safety hazards if he drinks it regularly.
Distilled water has its own function, and distilled water is free of bacteria, so it is relatively pure water without some microorganisms in it. However, distilled water has no nutrients in it, and distilled water is generally used in the pharmaceutical industry, which can be used to flush some surgical wounds and avoid the entry of bacteria. Moreover, distilled water can be used in the electrical industry, because it does not conduct electricity, which can help the normal operation of the machine and extend the use time of some electrical appliances.
Distilled water can also be used in chemical experiments, and at this time, distilled water is electrolyte-free.
Yes, and there will be no free ions in it, and there will be no impurities. Moreover, distilled water can also reduce some blood viscosity, and many people may have some cardiovascular and cerebrovascular conditions.
At this time, the viscosity of the blood is relatively high, so it is more effective to drink some distilled water. In addition, distilled water can also help people get rid of toxins from their bodies, so drinking it in the short term is good for your health.
-
Distilled water can be boiled and drunk, distilled water can effectively reduce blood viscosity, and can also eliminate toxins from the body.
-
Distilled water can be drunk with cherry blossoms, but it should not be drunk for a long time; The function of distilled water in the medical field: return to the medical community distilled water to flush surgical wounds; Chemical experiments use distilled water without electrolytes; Short-term consumption can actively absorb toxins from the body and eliminate them.
-
Of course, you can boil it and drink it, distilled water is a relatively pure water, which can be used for daily drinking or chemical experiments.
-
1. Distilled water cannot be drunk after heating, distilled water is obtained by heating the water, so that the water is vaporized, and the water obtained after condensation will lose a lot of minerals in the process, and symptoms such as dizziness and nausea will occur when drinking a large amount.
2. After distilled water is heated at high temperature, the nitrate in it will become nitrite, which will cause harm to hemoglobin in the blood, so that people's blood pressure will drop, and if it is not controlled, it may be more serious.
-
Distilled water can be boiled and drunk, but it is not recommended to drink it for a long time. Distilled water is water that removes microorganisms, bacteria, and minerals from the water through multi-layer processing, and is often used in pharmaceutical preparations and chemical experiments. Distilled water is pure water, but most of it has been repeatedly processed, which may produce ingredients that are not good for the human body, so distilled water can be drunk after boiling, but not for a long time, so as not to affect the body.
If you drink distilled water for a long time, it will lead to the loss of inorganic salts in the human body, and you will also lose the opportunity to obtain the necessary trace elements from the human body**, which is still harmful to your own health.
Distilled water is still relatively common in daily life, simply put, it is the small water droplets formed by the liquefaction of ordinary water after boiling, such as the water droplets produced when steaming rice and steamed buns.
The role of distilled water.
1. Because distilled water is non-conductive, it is often used to maintain the stability of machine operation and prolong the service life of electrical appliances.
2. For patients with chronic cardiovascular and cerebrovascular diseases and high blood thickness, drinking distilled water appropriately can reduce blood consistency, thereby protecting cardiovascular and cerebrovascular diseases.
3. Although distilled water cannot be drunk for a long time, short-term drinking can bring out the garbage toxins in the body, which is beneficial to good health.
4. Because distilled water has a hypotonic effect, distilled water is commonly used to rinse the surgical wound during surgery, so that the harmful cells that may remain on the wound surface absorb water and swell and lose their activity, so as to avoid the secondary growth of harmful cells.
5. Distilled water is commonly used in the school chemistry laboratory, because there are no free ions, no electrolytes, and no impurities in the distilled water, which will not affect the effect of the experiment.

Water heating or allowing the temperature to rise can turn into water vapor into the air, and water vapor in the air can become fog, dewdrops, rain, snow, hail, etc. If the temperature is too low, the water can freeze directly. Water can also be turned into hydrogen and oxygen, among other things.
Water is a colorless, tasteless, and odorless liquid at room temperature. Many common gases can be dissolved in water, such as hydrogen, oxygen, nitrogen, carbon dioxide, inert gases, etc., and the solubility of these gases is related to factors such as temperature, pressure, and partial pressure of the gas phase.
Pure water prepared by the distillation method. Distilled water can be divided into single and multiple times. After a distillation of water, the non-volatile components (salts) remain in the container and the volatile components (ammonia, carbon dioxide, organics) enter the initial fraction of the distilled water, usually only the middle part of the fraction is collected, which accounts for about 60. >>>More
Yes Distilled water does not have a trace of bacteria, but it should not be drunk for a long time because there are no trace elements in distilled water.
You can use a pot to boil water to collect distilled water, after the water boils, find a few more cold pot lids, and control the water droplets of distilled water into the container on the inside of the lid. >>>More
Difference Between Purified Water and Distilled Water.
Purified water is a clean aerobic molecule that contains trace amounts of mineral plants needed by the human body, and is also living water (fish do not die in it). Whereas distilled water is stagnant water (without oxygen the fish will die immediately in it). Purified water is not the same thing as distilled water at all, so distilled water cannot be compared to purified water. >>>More
Preparation: a small bowl, pot, water, ice cubes.
3. Heat the water in the pot below, as shown in the figure below. >>>More
