Legal aid, there is precipitation in the mineral water

Netizen Hao Duoduo, hello! Hope mine satisfies you!

First of all, minerals do not precipitate, so we can preliminarily assume that these precipitations represent a quality problem with the mineral water. As for whether it is actually or not, you can take it for further testing. Any testing company and quality inspection center can be.

Now let's talk about the case. Your situation is a very common behavior of merchants infringing on the rights and interests of consumers in the society, that is, merchants manufacture counterfeit and shoddy products for consumers to use, and consumers cause or may cause serious damage to their own health after use.

In this case, you can do two things: 1) report to your local consumer rights protection association; 2. Direct prosecution. Rest assured, you have a point, and I believe you have enough proof.

As for why they give it to you, they produce water with such quality problems, which makes you have the threat or possibility of health damage.

In addition, I will also tell you that the nature of your problem is a product quality infringement, and in the lawsuit, as long as the merchant cannot prove that there is no problem with the mineral water they produce, they may lose the lawsuit and they will give you compensation. Of course, if you are troublesome to fight a lawsuit, please ask the consumer association to come out, and the effect is similar. Recently, I have done my best to "3.15", this kind of behavior that not only protects your own rights and interests, but also helps the society to eliminate harm, anyway, I personally encourage you to do it!

Boredom If you find it bad, you won't drink it.

Have that energy to care more about the things that should be cared about!

After a long time, there are precipitation reasons in the mineral water:

Those precipitates are calcium carbonate. There are calcium ions in mineral water, and the carbon dioxide dissolved in the water continuously generates carbonic acid, and the calcium ions produce calcium carbonate, which also promotes the accelerated dissolution of carbon dioxide and further promotes the generation of calcium carbonate. Over time, more and more calcium carbonate will be precipitated.

Mineral water is unpolluted underground mineral water that springs naturally from deep underground or is artificially exposed; Contains a certain amount of mineral salts, trace elements or carbon dioxide gas; Under normal circumstances, its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range. Mineral water is formed by circulation in the deep stratum and contains minerals and limited indicators specified in national standards.

Mineral water usually has the presence of CA ions.

It reacts with CO2 in the air to form insoluble CaCO3, forming a white precipitate.

There are also certain Ca ions in soda, but in soda is CaCO3 precipitation produced by CaHCO3 decomposition.

They are not harmful to the human body.

Reaction formula: ca+CO2==caCO3

2cahco3==ca^+h2o+co2+caco3↓

Mineral water is due to the presence of minerals.

I have a simple experiment to prove it:

The sample is smeared on a glass plate and baked on a flame, and after a while, some solid material will appear on the glass plate. I don't believe it for myself.

Mineral water is found in nature. Calcium is ubiquitous on Earth.

In mineral water there are calcium ions, and in mineral water there is air, and there is air in the air.

Carbon dioxide reacts with these ions to form a precipitate.

In addition, calcium bicarbonate is also soluble in water, and calcium carbonate precipitates are formed when decomposed at normal temperatures.

Small amounts of CA compounds can also be supplemented with calcium.

You don't have to worry too much, it's normal, it's not that the water is contaminated.

Natural spring water is slowly filtered for thousands of years, and mineral salts such as calcium and magnesium are saturated. When boiled or frozen, the temperature and pressure change, and some mineral salts, such as calcium carbonate and magnesium carbonate, are precipitated in tiny white crystals, which are called "white precipitates".

It does not change the quality of the product and is harmless to the health of consumers, but it is unsightly.

According to the "GB8537-2008 National Standard for Drinking Natural Spring Water", the sensory requirements of "a very small amount of natural mineral salt precipitation is allowed, but there shall be no other foreign substances", which is also in line with the national health and safety standards.

In addition, you can drop a few drops of vinegar in the water, wait for at least 20 minutes, and see if the vinegar drops can be dissolved in the water.

If it really doesn't look good, it is recommended to store the natural spring water in a cool, dry place, refrigerated rather than frozen, and heated at no more than 70 degrees Celsius.

First and foremost, don't drink it anymore! It may be the bleaching powder of filtered water, but it depends on identification.

Of course, boiled water can be drunk, but if you boil it, you don't have to buy brand water. It's all the same.

What are you asking? Is Aikua the name of mineral water? If this mineral water is not good, you can change it to something else, if you like to praise the sediment in the mineral water. Sorry, I really don't understand what you mean.

Now it's like this for a long time, you don't see the dirty, you don't see the process of making, you eat all the time, and you don't dare to eat anything when you know it.

I also saw two bottles today, and it's clear that I don't plan to buy this in the future.

That's for sure.

My family is rural, and I drink the most natural unpolluted mountain spring water every day. But every time you boil the water, you pour it out, and you find a room of white minerals precipitating under the vessel. So I suggest that if you buy water that contains minerals, it's best not to boil it.

It's not true that drinking cold water will cause stomach aches, as you city people say, and it's better for children to give them a little more natural mineral water to be better for their health.

No way, it will only increase the solubility of the water!

Weird. Try it and you'll find out.

In this case, it is likely that the calcium and magnesium ion content is too high, and the general water purifier only filters sediment, rust, bacteria, etc., if you want to completely remove impurities, it is recommended to use a water purifier.
