Water myths: can boiled and unboiled water be mixed? Can antifreeze be mixed with water What happens to raw water when mixed with boiled water.

One of the rather old urban legends says that you cannot mix boiled water with unboiled water for drinking. Among the beliefs about the consequences of drinking such water, there are many options, ranging from poisoning with nausea and vomiting, ending with a decrease in immunity and the development of a number of diseases with their further transition to the category of chronic ones. No one can provide any objective reasoning why all this should happen and what kind of chemical processes take place there.

Rumors about "dead" water and its dangers

One of the most common justifications for the myth is that after boiling water becomes "dead", and its mixing with "living" raw water does not allow the body to recognize what it is actually given. Allegedly, in the so-called "dead" water, together with all microorganisms, after boiling, all useful properties and other substances die. It's funny, because salts, which are the main useful substances dissolved in water, will not disappear during boiling, perhaps only their concentration will slightly decrease. Vitamins in it will not decrease, because they are most likely simply not there. But the stories about "dead" water is an unfounded legend, which has no scientific confirmation.

Rumors about the dangers of water memory

In second place is the theory of the memory of water, according to which the body can assimilate only homogeneous water, and boiled water, mixed with unboiled water, remains heterogeneous further. The talk about the memory of water has been going on for a long time, but most often it turns out to be nothing more than inventions for a successful fraud with the sale of water charged for success, health and treatment of certain diseases. We all remember the tricks about charging water from the TV screen, but the maximum that could be obtained from such water is the placebo effect.

And so all the main arguments of the supporters of the veracity of the legend turned out to be unconfirmed from a scientific point of view and unconvincing even from the point of view of simple logic. No confirmation, only beliefs that this should not be done. Now let's turn to the logical side of the question of whether it is possible to use mixed boiled water with unboiled water.

What happens to raw water when mixed with boiled water?

In fact, mixing boiled water with raw water will simply turn out to be unboiled water again in all its properties, which are important for human consumption. If unboiled water from a specific source may contain bacteria and viruses, they will be transferred to the boiled water when mixed. Yes, their concentration will drop, but a small amount of unboiled water with their content is enough to spoil a large amount of boiled water. That is, from a microbiological point of view, it is impossible to mix raw water with boiled water for the same reason that you cannot simply drink raw water.

In terms of the composition of impurities in water, their concentration decreases during boiling. Chlorine comes out with steam when the water is heated, various elements are deposited in the form of scale on the heating elements. Therefore, mixing boiled water with unboiled water will simply lead to the fact that the composition of the final mixture will turn out to be more similar to the composition of unboiled water, elements that could have come out completely during heat treatment will again appear in it. It turns out that from the point of view of the chemical composition of impurities in water, mixed boiled water with unboiled water will be more similar to unboiled water.

That is, from a scientific point of view, nothing terrible will happen when mixing, just the mixed water will actually be unboiled with all the ensuing consequences. For some sources of water, drinking it raw is dangerous, for some it is quite safe, for example, if it is tap water. If you use filtered or bottled water, then all the more there will be no negative consequences. Trust unfounded rumors less and choose your water sources more carefully!

A question from a reader.

« Good day Sergey. Can you please tell me if it is possible to mix antifreeze with water. The thing is that I have a low level of antifreeze, and it is not realistic to buy now, I am on vacation, I write from a tablet. So I think if it can be diluted with plain water? Isn't it dangerous? I'm waiting for an answer Sergey, respect for the site, he really steers, even on vacation helps»

Guys, write your names! This will make it more convenient to communicate in the article!


In principle, antifreeze and antifreeze are practically the same thing (more details). Therefore, if you read the article on my site, you will understand everything.

However, for you I will repeat myself. Yes, and they ask this question a lot, to my mail - is it possible to mix antifreeze with water.

So, antifreeze is a type of antifreeze, it consists of ethylene glycol, and special additives. It was developed in 1971 in the USSR. Distinguished by concentration, grade 40 has a blue color, the most common in Russia, it is it that is poured into many Russian cars, it remains liquid up to - 40 degrees Celsius. There is also a red antifreeze, grade 65, used mainly in the northern regions of our country, thickens at temperatures below - 65 degrees Celsius.

Now to the point. Of course it is possible, antifreeze consists of about 60 to 70 percent of water, and only the rest is additives and ethylene glycol. In summer, at high temperatures, water from antifreeze, respectively, the level drops. Unless of course you have a radiator leak. Therefore, if you "catch up" the level of antifreeze by adding water to the norm, there will be nothing wrong with that. The main thing is not to overdo it. No need to pour too much water. Remember - with a cold engine, the level of antifreeze may drop, because the cooled liquid has a lower level than the hot one.

Again, in the summer you can ride even with a weak solution of antifreeze (that is, a lot of water added). But before winter, you need to replace such antifreeze. Diluted antifreeze loses its temperature regime, and even at minimum temperatures it will simply freeze.

Also, it is not necessary to greatly dilute the antifreeze also because the anti-corrosion properties of the liquid fall. The more water in the antifreeze, the more chances that the car's cooling system will rust.

And the last thing, if you are on vacation and have nowhere to buy antifreeze, buy a five-liter canister with ordinary drinking water at the nearest store, and bring the antifreeze to the level. You can ride on such a liquid even until the first cold weather, - 1, - 5 degrees Celsius. But then replace it, it will be better for the engine itself, and for the engine radiators and stove.

In this article, we will discuss with you common rumors about can antifreeze be mixed with water.

Is it true that coolant (antifreeze or antifreeze) can be mixed with water? Such questions arise mainly in the summer season, when the chances of engine overheating increase sharply ( why is the engine overheating?).

Can antifreeze be diluted with water?

Every experienced motorist knows to monitor the coolant level in the system as often as possible. If the level of the coolant in the tank is below the "minimum", and you need to add just a little bit. The question immediately arises buy expensive antifreeze or you can add some plain water to antifreeze?

In the summer season, many motorists are interested in the question mixing antifreeze of different colors, but we will talk about this in the next article. Let's still define can antifreeze be mixed with water?

If you ask for help from the rules of technical operation of the car, offered by the manufacturer, then there is no place for such conversations. Manufacturers categorically prohibit any spontaneous mixing antifreeze with water.

Mixing antifreeze with water is prohibited for the following reasons:

  1. Antifreeze contains special additives that have the necessary cooling and lubricating properties. AT the case of mixing antifreeze with water their effect is significantly reduced.

If you do not have money, or there is no car shop nearby where you can buy antifreeze for refilling, you can add water to the cooling system . What happens if antifreeze is mixed with water?

Using water as a top-up in the engine cooling system is possible, but for a short period of time, and is not recommended. can lead to corrosion of aluminum engine parts, clogging of the radiator of the cooling system, and a decrease in protective properties. Dilution of antifreeze with plain wateris fraught with negative consequences, therefore, the option of adding water to antifreeze exists, but this has its own risks. Domestic cars more easily perceive such a combination, but on foreign cars, I would not recommend trying this a mixture of antifreeze and water. If you did not have a choice, and you refilled the cooling system reservoir with water, in the near future you should completely replace antifreeze in the engine... Moreover, if you decide to add water to the antifreeze, then in any case, you should use distilled water. It is forbidden to fill in ordinary water. Using plain water as a coolant will damage parts of the cooling system.

Is it possible to mix antifreeze with water in summer ?

Mix antifreeze with distilled water it is possible, only for a short period of time, if there is no possibility of antifreeze filling in the vicinity.

Adding water to antifreeze in winter is strictly prohibited, it can lead to "block defrost". The water will simply freeze and damage engine parts. If in the summer you even added a little water to antifreeze, then before the onset of cold weather, be sure to completely replace the coolant with antifreeze... It is advisable to use high quality antifreeze, the use of water as a coolant is history.

Don't be confused! Antifreeze concentrate is mixed with distilled water!
