Is pure water better than tap water and why write a short paragraph of justification

Each has advantages: pure water contains almost no impurities, so you don't have to worry about bacterial and parasitic infections when you drink cold, the disadvantage is that it does not contain minerals and trace elements, and some substances must be replenished by drinking water, so people who drink pure water for a long time will be tired and weak; Bleaching powder is added to the tap water, but it generally does not exceed the standard, and as long as it is boiled, it can kill bacteria and insect eggs.

First of all, don't copy the articles of experts, it's really sad to trust experts these days.

This kind of simple question, everyone has a brain, just think about it and understand it.

The tap water process was born 100 years ago, when there was no industrial pollution, and it was sufficient to remove sediment by flocculation and microorganisms by chlorination. However, the process that has not been used for 100 years has not been able to remove heavy metals and pesticide pollution.

Pure water, very clean, so clean that there was nothing in it. So much so that some experts worry that it is too clean, so clean that there are no minerals, and it is unhealthy to drink it for a long time. But there is no experimental data, whether there are case reports, there are none.

So what are the conclusions of the experts, and the hat on the heads of the experts?

Since there are no minerals in drinking pure water, none of the experts have made it clear what minerals are in drinking tap water. So I went to check the food nutrition table myself, and the result was:

Calcium 30mg l is only 1 50 of milk, and more than 80% of calcium is lost during the boiling process of tap water, and it becomes limescale to supplement calcium in the kettle. Other:

Potassium 2 mg l is 1 1000 of soy milk

Zinc, is flour 1 2340

Iron, which is 1 200 of egg yolks

It can be seen that the minerals in tap water are negligible and can be obtained from a wide range of diets. Drinking tap water at the risk of being polluted by pesticides and chemicals for the sake of a few minerals is really worth the cost. Unless someone is willing to use the body as a filter.

The public says that the public is justified.

Po said that Po is reasonable.

There are both advantages and disadvantages.

Water does not contain other trace elements.

Tap water and purified water, on the other hand, contain substances other than water and are not pure.

Definition. It is defined as follows:

1. Pure substance refers to a polymer composed of a single substance or a compound, which is fixed in composition and has fixed physical properties.

and chemical properties of substances, which have special chemical symbols and can be represented by a chemical formula.

2. Tap water refers to the water produced by the tap water treatment plant that meets the corresponding standards for people's life and production.

3. Purified water refers to Ho without impurities, referred to as clean water or pure water, which is pure, clean, and does not contain impurities or bacteria, such as organic pollutants and inorganic salts.

Any additives and all kinds of impurities are in line with the sanitary standards of drinking water.

of water is raw water.

Characteristics of pure substances.

1. Substances with fixed composition and fixed physical and chemical properties.

2. There are special chemical symbols.

Examples: oxygen, nitrogen, potassium chlorate.

and so on, all of which are pure.

Conception. Macro: A polymer made up of one component.

Microscopic: Composed of particles of the same kind.

In the real universe, pure matter is only a theoretical state.

Tap water, purified water contains other impurities.

Water is pure, water consists of only one substance, a substance with fixed physical and chemical properties, and a special chemical symbol.

Tap water, purified water, in addition to water, also contains an impurity element such as salts. So, tap water, pure water is not pure.

1. There are broad concepts and narrow concepts, the broad concept is the various types of water we see, and the narrow concept is H2O.

The question should be a narrow concept.

2. Tap water is a mixture (solution) with water (H2O) as the main body, and purified water is a mixture (solution) with water as the main body and relatively few impurities.

3. Obviously, only water (H2O) is pure.

Tap water contains a lot of impurities, and the water is pure after filtration.

This is a chemistry problem, because tap water and pure water contain impurities.

Strictly speaking, mineral water as a beverage can only be consumed by 500 ml per person per day. If in excess, its contents.

Fluoride. It is quite detrimental to the human body and can even have serious consequences. Therefore, no matter how good mineral water is, it can only be used as a drinking material, while purified water is not, it will not have a negative impact on the human body, but can help excrete toxins in the human body.

From a scientific point of view, everything has a dual nature. Therefore, compared with mineral water, although pure water removes harmful substances and nutrients in the water, it is ultimately harmless to human health. At present, some people think that pure water is too pure and has no nutrients at all, but they do not know that 95% of the nutrients required by the human body are ingested from food.

If it's not pure, then what is it called pure water? Generally speaking, the main forms of impurities in water are gases and liquids.

Droplet. Suspended solids in water.

Solid particles and microorganisms, etc., their concentrations vary with the amount of emissions

Turnover. and changes in climate and other conditions. With so many contaminants, how can they be drunk after only superficial treatment?

Mineral water, on the other hand, is only shallow filtered, so it retains minerals and nutrients while also retaining harmful substances. And hazardous substances are usually contained.

Carcinogen. The effect of the substance is none.

Thresholds. , even in the smallest amounts, will produce a certain reaction. Therefore, purified water is a safe daily drinking water in the long run.

According to industry insiders, in the production process, the production cost of pure water is higher than that of mineral water, which reminds me of ".

Nongfu Spring. Why is the production of pure water discontinued?

In the end, some people say that foreign countries do not drink "pure water" and do not set "pure water" standards at all, which is misleading consumers and deliberately confusing the public. It needs to be corrected that "pure water" is not the same as "pure water". Of course, "pure water" cannot be drunk, it is used in special industries, and of course it cannot be used as drinking water.

Who said purified water is better than mineral water?

Purified water has been purified multiple times, with very few impurities and no minerals that are beneficial to the body.

Mineral water is a slag that adds some minerals necessary to the human body to the water.

I think it's better to drink mineral water, drinking too much pure water is harmful to human health and can't be drunk for a long time, Song.

1 All purified water refers to H2O without impurities, also known as distilled water. But the "pure water" in the water dispenser in our life is not really pure, but the tap water is processed and purified. Mineral water has some metal ions and trace elements in it, so it is not pure water.

Boiling water can only further evolve the water quality, but it is not up to the standard of pure water. In fact, the purity of water in daily life is generally that pure water is greater than boiling water, larger than tap water, and greater than river water.

Pure hand play, hope lz adoption!

Purified water, because it does not contain organic pollutants, inorganic salts, additives and various impurities, is safer as domestic water. It can be boiled without burdening the heart and kidneys. Purified water is oxygen-rich water, which activates cells, strengthens immunity, promotes metabolism, and cooks meals with purified water will be more fragrant.

How is purified water made? It is prepared from water that meets the sanitary standards of drinking water as raw water, and is prepared by electrodialyzer method, ion exchanger method, reverse osmosis method, distillation method and other appropriate processing methods, sealed in a container, and does not contain any additives, colorless and transparent, and can be directly drunk. The best space water and distilled water on the market are pure water.

In China's bottled drinking water market, there are mainly pure water, mineral water, spring water and natural water, mineral water, etc., because mineral water, spring water, etc. are limited by resources, and pure water is produced by a certain production process using tap water, so the people on the market drink the most or pure water, the quality of pure water and the lives of the people have a close relationship.

From a chemical point of view, pure water is pure H2O. This 'pure' is the same as the purity of pure sulfuric acid, which means that the concentration is 100%;H2O is the chemical formula of water, and I have relevant knowledge in junior high school chemistry class.
