There is a lot of limescale when boiling water, why does some water have limescale after boiling, wh

Water contains a certain amount of minerals, and these minerals will be deposited during the boiling process to form scale.

When cooking porridge, certain minerals will react with some chemicals contained in the porridge, and the scale will not be visible.

Even if it is limescale, it contains some calcium sulfate, magnesium sulfate and other substances, these substances are not toxic, but can not be digested and absorbed.

Boiling water for 3-5 minutes can better kill germs and eggs, and the nitrite level produced is within a safe range. Cooking porridge will definitely produce a certain amount of nitrite in the water, but compared with these, the nutrients in the porridge are more than excessive. Moreover, our Chinese porridge has a history of thousands of years, it is conducive to digestion and absorption, reduces the burden on the stomach, and is definitely a good thing.

You didn't graduate from high school! Tap water contains some soluble calcium and magnesium compounds, and when the water is boiled, these calcium and magnesium compounds will precipitate down to form scale! (Well water and river water have more calcium and magnesium compounds!)

If there is too much scale, it will affect the effect of boiling water, because these scales are very heat-absorbing and will consume a lot of calories in vain, and if you do not remove the scale regularly, once the scale is too much, it will cause **, which is very dangerous! So be industrious!

The tap water is all treated! There are not a lot of calcium and magnesium compounds (the calcium here is not the calcium our body needs!). Attention! The effect on the human body is not very large! The main thing is to kill the microorganisms and bacteria in the water.

So! Rest assured!

This depends on the presence or absence of impurities in the water, as natural water in general burns limescale to a greater or lesser extent, as does mineral water, but not purified water.

Because there is a lot of sediment and the water quality is excellent, the main reason is that the calcium and magnesium ions are too high, and the sediment is adsorbed on the magnesium ions, and the sediment will form scale when it precipitates, while the filtered water will not, such as pure water.

Scale is a precipitate of water-soluble compounds as well as a mixture of impurities. Compounds of calcium and magnesium ions (e.g., calcium carbonate, calcium chloride). Most of them are insoluble in water, and the main ingredient of limescale is calcium carbonate and does not have much impact on health, so it will have an impact on the kettle, and it can be removed with vinegar.

The amount of limescale is caused by the amount of minerals contained in the water, and it is not that the less limescale, the better the water is for the human body.

In "Confession of Scale", the scale "self-says" that there is scale in the water, indicating that the water quality is "hard", which indicates that it is alkaline water and contains mineral nutrients; If there is no scale, it is usually acidic water, which will take calcium ions from the bones or blood of the human body, and is called "bone scraping water".

In daily drinking water, as long as it meets the national sanitary standards for drinking water, no matter whether the water is "hard" or "soft", it is harmless to the body.

Do you mean that there will be a gutter when the water is boiled cold, and the answer is that there will be almost none.

In daily life, the inner wall of the kettle will be scaled after a long time, which is related to the hardness of the water. Mainly calcium bicarbonate [Ca(HCO3)2] and magnesium bicarbonate [mg(HCO3)2] dissolved in water, during the boiling process, they will become calcium carbonate [CaCO3] and magnesium hydroxide [mg(OH)2], which are insoluble in water, so that scale is formed. Limescale attached to the inner wall of the kettle will affect the thermal conductivity of the kettle wall, resulting in waste of energy.

China's "Sanitary Standard for Drinking Water" (GB5749-85) stipulates that the index value is: 450mg L.

The softness and hardness of water depend on the content of soluble calcium and magnesium compounds, and the World Health Organization (WHO) classifies the hardness of water according to the standard of "the quality of calcium ions and magnesium ions in 1L of water"; The higher the calcium and magnesium ion content, the higher the hardness of the water.

For drinking water, the hardness will affect the taste of the water, generally water with low hardness feels soft, and water with high hardness feels refreshing and heavy.

Some people think that drinking water with more limescale will increase the risk of stone disease and other diseases, experts said: the generation of limescale is a physical phenomenon after the water is boiled, and stone disease is a physiological phenomenon of the human body, "these two are not the same thing".

It is related to the water quality, that is, the substance content of the water itself is different. At high temperature, calcium sulfate containing slightly soluble in water will precipitate due to the evaporation of water, and the carbonate in the water will combine with calcium and magnesium ions to form calcium carbonate and magnesium carbonate that are insoluble in water, that is, water alkali. With the continuous evaporation and concentration of water, the water alkali content continues to increase, and scale is formed after reaching saturation.

Buy an older loofah, the inside is dry, dig up the seeds, leave only the net-like thing, and put it in the kettle when boiling water....

Then you can cook porridge in boiling water or mineral water. Personal thoughts.

You can crush it with an eggshell, cook it in it and it's gone, it's not a big problem, it's called water quality stones! No one has this at home! ~

If you are not dry, you can cook porridge with boiling water, if you have limescale, you can put a clean cotton cloth in the kettle, absorb, effective, but also, precipitation 3-5 minutes and then flush into the water bottle is better, no matter what so much to do, from childhood to adulthood is not like this...

After boiling water, a lot of scale is high in calcium and magnesium ions in water, which is common in the form of calcium carbonate and magnesium. The national drinking water regulations are expressed in terms of total hardness, calculated by calcium carbonate, which is less than or equal to 450 milligrams per liter, and the water of natural rivers and lakes is generally about 100, and the water of deep wells is higher, up to more than 1,000.

Total hardness in water is divided into total hardness, temporary hardness, and permanent hardness. After boiling and precipitating, calcium and magnesium ions are removed, and the remaining measurements are potassium and sodium ions, which are called permanent hardness, and the sum of the two is the total hardness.

The high total hardness can cause a small number of people to be unaccustomed to the soil and water, washing with soap will reduce the cleaning effect, and boiler water will cause danger. Some people reported that this water ion is high, and drinking it is good for cardiovascular prevention.

Because the total hardness is in the form of calcium carbonate and magnesium, just like adding alkali to water, this boiled porridge is harmless and fragrant.

This water has a high calcium carbonate content, and scale is the result of calcium carbonate precipitation in the water.

Water containing more than a certain amount of calcium is called "hard water", and drinking too much hard water will definitely have certain adverse effects on the human body. Because a large amount of calcium carbonate deposits in the human body may also form so-called "scale" in the stomach and intestines, etc., affecting the digestive function of the person.

For hard water, it can be used safely after softening. There are a lot of water purifiers on the market at present, buy one. Pump up the well water and store it in the water tower, and then use a section of water pipe to lead it out, and add a water purifier in front of the faucet to have a certain effect.

As for the professional hard water softening method, it is more troublesome, and it should be said that it is okay to use a water purifier.

It is caused by the fact that the water quality of your local tap water contains too much alkaline substances, and you can remove the scale by soaking it in a hot water bottle with egg shell and vinegar for 24 hours.

The kettle is always full of limescale after boiling water, add a few drops of it to keep your kettle as clean as new.

Many people are boiling tap water to drink, the water quality in the north is hard, after boiling, the scale produced is more, some people think that drinking water with scale, the body will have stones, is this really the case?

Available Items:

Soak the lemon in water for a while.

Vinegar yogurt (more luxurious).

Explanation: Scale is mostly water concomitant than calcium carbonate This mixture can be neutralized and diluted with acids The cleaning effect has been achieved.
