Can I freeze vodka before ice

Since ancient times, people drink alcohol in theor other form. We will not argue about the harm of such drinks. Alcohol is really harmful to health, but most people believe that it can be consumed in small quantities.

Vodka is a strong alcoholic drink, consisting of water and ethyl alcohol. The fortress is regulated by GOST - it ranges from 40 to 56%. The most common and popular option is vodka 40%.

Russians often use vodka as aindependent alcoholic beverage, and foreigners as the basis for cocktails. In addition, it is used for the production of tinctures and lotions, for compresses and rubbing. In fact, a universal product, and not just for people who drink.

Many people mistakenly believe that vodka was invented by D.I. Mendeleev. In fact, this product appeared much earlier, even in Persia. And Dmitry Ivanovich worked a lot and densely on the properties of solutions, including alcohol. His doctoral dissertation was titled "On the alcohol with water", where it is scientifically justified ideal fortress - 60 parts pure alcohol and forty parts.

For the first time in our country, vodkaDmitriy Donskoy, but the innovation did not interest either the princes or the common people. They thought that our honey and bread wines are much tastier. In 1429 vodka was brought back to Russia, but already as a medicine. Since then, it has taken root in our lands.

Water-alcohol solution, like any other,has different physical and chemical properties: there is a freezing temperature of vodka, the ability to react with certain substances, but many people are only interested in the effect of this drink on the human body.

It has long been noted that alcohol in small doses(about 20-25 g of alcohol) relaxes, gives a pleasant ease and ease in communication. However, with the increase in dosage, such negative consequences as the loss of coordination, a decrease in attention, the lack of an adequate assessment of reality and one's own behavior begin to increase rapidly.

The only useful quality of vodka from a medical point of view is its disinfecting properties, as well as the possibility of using as lotions, compresses and cooling refreshing rubs.

Few people know that vodka and alcohol have been trieduse as an anesthesia (in the absence of other drugs), but this method had to be abandoned. Too thin line lies between the loss of sensitivity and the unconscious state (as it is necessary for the operation), as well as a fatal outcome.

A lot of people are wondering ifthe principle of freezing vodka. The answer is simple - yes, like any other liquid mixtures. For example, a saturated solution of sodium chloride crystallizes at -21 ° C, and calcium chloride at -55 ° C. Pure ethanol freezes only at extremely low temperatures (-115 ° C), arctic fuel at -50 ° C.

So the question is not whether vodka freezes, but at what temperature this process takes place. Let us dwell on this in more detail.

At the end of the 18th century the French scientist FrancoisRaul studied the decrease in the crystallization temperature and the decrease in vapor pressure (increase in the boiling point) of the solutions with a change in the concentration of the introduced substances, and derived several laws of the behavior of ideal solutions.

The second law of Raul says that lowering the boiling point and raising the freezing point of the solution is directly proportional to its molar concentration.

The law is applicable to infinitely dilute solutions, and the nature of the introduced component does not affect it.

Is this law suitable for water-alcoholsolution, and what will be the freezing point of vodka according to Raul's conclusions? All the laws of Francois Raul apply to ideal solutions of non-volatile substances, and alcohol is very volatile and creates an increased vapor pressure above the surface of the water-alcohol mixture. So it can be calculated with a slight error: the freezing temperature of vodka 40% is -27 ° C.

Immediately it is necessary to say what to say about freezingat this temperature is incorrect for some reason. During the crystallization, water ice cubes form, and in the remaining mixture the alcohol concentration increases, and, consequently, the freezing point of the liquid mixture changes. So from a scientific point of view, it's correct to speak not about the freezing point, but about the point of the beginning of the crystallization process.

Partially by experience, a table of the dependence of the freezing point on the amount of alcohol in vodka was formed in part by formulas.

The freezing point (the beginning of the crystallization process), ° С

The freezing point of vodka can varynot only on the change in the concentration of alcohol in the mixture, but also on the presence of other substances in the solution. Even classic vodka, which consists only of purified water and alcohol, contains a certain amount of fusel oil and other impurities. And after all, there is a drink with different flavors that affect its physical properties.

So, we determined that the temperature of the startcrystallization of 40% of the water-alcohol mixture is -27 ° C, but only approximately. In general, it can be said that the freezing will begin when the mark on the thermometer approaches or crosses the boundary -30 ° C.

In the freezer, the temperature, depending on the settings, can be -5 to -24 ° C. However, this is still not enough to freeze 40% of alcohol.

Many people were faced with the fact that the vodka left in the compartment for frozen food thickened and ice was formed in it. So why did the vodka freeze in the freezer?

There are several options. First, the product may be diluted, and instead of 40% it will not be more than 35%. And with a decrease in concentration, the freezing temperature of vodka will decrease, and the capacity of the freezer will be enough for crystallization.

The second option - the actual temperature in the freezer is much lower than stated. It is very simple to check with a regular street thermometer.

The third option is the leakage of coolant,because of what in the refrigerator regions with extremely low temperatures are formed. This, by the way, is a rather dangerous situation - freon evaporates, and the compressor in the refrigerator overheats, resulting in the unit failing. In addition, freon adversely affects the environment and is one of the most dangerous substances that destroy the ozone layer.

Freezing vodka is a complex process thatit is difficult to imagine without a clear example. Frozen vodka can look different, depending on the concentration of pure ethanol, time, impurities, temperature fluctuations. However, at the initial stage, it does not crystallize, but thickens, sometimes even turns into jelly. To the traditional alcohol jelly, which is made from strong drinks, it has no relation. However, in a similar way, "intoxicating ice cream" is made. It looks like fruit ice, and it's very nice to eat in the heat. However, only adults, because children can not drink alcohol.

After thickening with further cooling, vodkabegins to crystallize - sometimes freezes by plates, sometimes in it separate islands of ice are formed. Turn it completely into a solid piece is problematic - it is due to the same increase in the concentration of ethanol in the remaining solution.

When vodka freezes, the question immediately arises as to whether it can be drunk. Theoretically this is not prohibited, but there are several nuances.

Firstly, if the vodka froze at a smalltemperature, and it already has a lot of ice, then, most likely, it is diluted and not made by technology. We do not recommend this, although you can throw out ice and drink the remaining liquid, in which alcohol will be more. Previously, this method of cleaning vodka was used - freezing, when excess water froze, and the remaining mixture became cleaner and better.

Secondly, frozen vodka should be drunk very muchCaution. Strongly chilled, viscous, it practically does not smell and does not taste, and the cold additionally dulls the receptors. Therefore, you can drink it very much, and then instantly and strongly intoxicated, which leads to severe toxic poisoning.

So if you are not an opponent of alcohol, then use it at least correctly, so that there are no unpleasant consequences.
