On the question for distilled water, what is distilled water

1.Is distilled water a natural drink?

Answer: Distilled water is water of high purity obtained by evaporating --- condensing water, which is artificially made and is not a pure natural drink.

2.Does distilled water contain chemicals?

A: Everything contains chemicals, distilled water contains H2O3Is distilled water purified water?

Answer: Although distilled water is very pure, almost pure, but no substance can be absolutely pure.

1.It's not natural, and the water on the lid of the pot when you cook is distilled water.

2.Of course there are chemicals, water, (what is not a chemical?) The food you eat and the water you drink are all chemicals)

3.Distilled water.

The production of distilled water is to boil the source water to evaporate and condense, which consumes a lot of heat energy, and the cost is not too low, and other hot evaporation substances in the source water used to make distilled water will also condense into the distilled water with the generation of distilled water, such as phenols, benzene compounds, and even evaporable mercury that are harmful to health. In order to obtain pure water or ultrapure water, it must go through two or three distillations and add other purification methods.

There are still some metal elements in today's pure water, but distilled water is real water.

To put it simply, it is the water that comes down after the water is boiled.

When the water is boiled, the evaporated water evaporates and leaks.

Distilled water (zhēng liú shuǐ) refers to pure water prepared by the method of distillation, which can be distilled both once and multiple times. After a distillation of water, the non-volatile components remain in the container and are removed, and the volatile components enter the initial fraction of the distilled water, usually only the middle part of the fraction is collected, accounting for about 60%. The types can be divided into primary and multiple distilled water.

The water that drip from the wall after you take a shower is distilled water.

Distilled water is a very pure water. It is a means of evaporation and condensation of substances with low boiling point in water to achieve the purpose of separating purer water, and distilled water can be divided into primary distilled water and multiple distilled water, which is often used in chemical experiments and medical operations, in addition to distilled water will also be used in work related to machines and electrical appliances.

Distilled water refers to the water processed by the thermodynamic separation process of "distillation", which can not use other solvents, but only use the characteristics of different substances with different boiling points to evaporate and condense the substances with low boiling points in the water, so as to achieve the effect of separating them.

Distilled water can be divided into primary distilled water and multiple distilled water, most of the primary distilled water also contains carbon dioxide, organic matter and other substances, while multiple distilled water can remove organic matter, carbon dioxide and other substances in the water with the help of potassium permanganate solution and other substances, it is also more pure.

Use. 1.In life, when it is generally related to machines and electrical appliances, the main role of distilled water is that it does not conduct electricity, ensures the stable operation of the machine, and prolongs the service life of electrical appliances.

2.In the pharmaceutical industry, the action of distilled water is due to hypotonic action. Rinse the surgical wound with distilled water to make the tumor cells that may remain in the wound absorb water and swell, rupture, necrosis, and lose their activity, so as to avoid the growth of tumors in the wound.

3.Some chemistry experiments in schools require the use of distilled water, which has no electrolytes, no free ions, or no impurities. You need to analyze the specific problem on a case-by-case basis to see if it is due to its non-conductive properties, or hypotonic effect, or if there are no other ions and no chemical reactions.

Distilled water is water that is distilled and condensed, and the second distillation is called re-distilled water, and the third distillation is called triple distilled water.

Sometimes for special purposes, appropriate reagents will be added before steaming, such as for ammonia-free water, acid will be added to the water; Water with low oxygen consumption, potassium permanganate and acids are added. Industrial distilled water is pure water obtained by distilled water method, the purity of the water obtained by ordinary distillation is not high, and the effluent can be very pure after multi-stage distillation, and the cost is relatively high.

Steps to make distilled water

1. Add water to the pot and heat it on the stove over medium-high heat.

2. Put the large bowl in the pot and let it float on the water, ready to use it to receive the distilled water.

3. Put ice cubes on the lid. The amount of ice you want depends on the size of the lid, and you can pour out the water and add new ice cubes, as the heated ice cubes dissolve quickly. These ice cubes are used to speed up the steam in the cooling pan so that they can trickle into the large bowl.

4. At this time, if you lift the lid slightly, you can see some steam condensing into water droplets on the lid and dripping into the large bowl.

5. As long as the bowl does not sink, you can try to accept distilled water until the amount you need.

Distilled water is also pure water.

Pure water is pure water, pure and has no taste at all. Pure water of qualified quality is not harmful to the human body, but this kind of water is not very natural, it has gone through many processes to filter harmful substances, and also filters good trace elements. Therefore, some people will say that drinking it is harmful, drinking it will cause nutrient loss, and drinking it for a long time will lead to a lack of minerals.

In fact, the real situation is that as long as you don't drink every day, every day, the impact is minimal, after all, the nutrients of the human body still mainly rely on dietary intake. Distilled water is common in our daily life, similar to the water on the lid of a pot when cooking. Distillation is only a means of purification, its essence is pure water, it is said that the tea brewed by this water is particularly fragrant, there are no impurities in the water, and the taste of the tea itself is naturally brewed.

Meaning of distilled water

Distilled water refers to water that has undergone distillation and condensation operations, and the second distillation is called heavy distilled water, and the third distilled water is called triple distilled water. Water with low oxygen consumption, potassium permanganate and acid are added, and industrial distilled water is obtained by distilled water. The entry introduces in detail the concept of distillation, distilled water, multi-distilled water, and the standard, production method, advantages, and uses of distilled water, and compares and analyzes it with deionized water, high-purity water, and ultrapure water.

Distillation is a thermodynamic separation process, which uses the different boiling points of each component in a mixed liquid or liquid-solid system to evaporate the components with low boiling point and then condense to separate the whole component, which is a combination of evaporation and condensation. Compared with other separation methods, such as extraction, filtration crystallization, etc., it has the advantage that no solvents other than the system components are used, thus ensuring that no new impurities are introduced.
