How do you inject carbon dioxide into water, like cola?

Industrially, first of all, let me say this, he also wrote in the raw materials, there is a thing called carbonated water.

In chemistry, this thing is a carbonated aqueous solution.

In other words, carbon dioxide dissolves in water to produce H2CO3 carbonate, which is very unstable and decomposes into water and carbon dioxide when subjected to pressure changes and violent shaking.

Therefore, the principle of his injection is that everything that has been made into a drink, before filling, it is passed into a pressure container (only 6MPa is enough) There is a stirring equipment in the container, and then constantly stirred, under high pressure, the carbon dioxide of the liquid is passed, and the carbon dioxide is liquid at 30 degrees under this pressure, so the container must also ensure that it is 30 degrees.

After an appropriate amount is in, stir well.

Then it is sent to another container, which is a low-pressure container, the pressure of the liquid in this container does not exceed, usually only, and then let the excess carbon dioxide run away, and the rest is dissolved carbon dioxide in water, that is, carbonated acid mixed with those other things into carbonated drinks.

They are then filled into bottles in a pressure chamber (the whole room has the same pressure as this container), the lid is closed, and then it is passed through a decompression chamber and sent outside, that is, the filling is completed.

All of this is done under pressure and automatically.

Also, I've talked about how it's filled, but I don't know what his recipe is, I just know that it's made from Coca-Cola's secret ingredients + water + carbon dioxide (i.e., carbonated water).

And then he has this carbon dioxide property, which is the answer to your question.

As for the formula of Coca-Cola, who knows what it is...

Carbon dioxide. It can only be incorporated into the water at low temperatures, and a certain amount of pressure needs to be applied. Carbonated drinks, like the cola you said are in the 10s Celsius.

The drink is mixed with carbon dioxide in a mixer. Thank you.

Blow into the bottle Remember, only blow, not suck

The jar was previously filled with carbonated water, which was treated at high pressure to dissolve a large amount of the waterCarbon dioxide. The carbon dioxide and water of carbonated water are 1:1, and the source may be several times or dozens of times after being pressurized.

Coke:

Cola, which refers to a sweet, caffeinated but non-alcoholic carbonated beverage.

Flavors include vanilla, cinnamon, lemon and more. The name comes from one of the early materials of Coke: kola nut.

extract, the most well-known cola brand is Coca-Cola.

and Pepsi. Drinking Coke was originally no different from drinking other beverages. However, the connotation of cola culture is too rich, far beyond the scope of "drinking drinks".

Cola is a carbonated drink that quenches your thirst, and its main ingredients are sugar water and carbon dioxide. Carbon dioxide has the effect of lowering the temperature and giving the cola liquid a sour taste, which can create a unique taste.

Therefore, during the production of cola, the bottle is pressurized or the temperature is lowered to allow the carbon dioxide to stay in the sugar water. Although carbon dioxide is insoluble in water, some of it forms carbonic acid in the water, which gives it a sour taste, which is the taste of cola. Carbonic acid is unstable, and carbon dioxide will decompose when it is exposed to light or shaken vigorously.

When the bottle is opened, the pressure outside is less than the pressure inside the bottle, and the carbon dioxide takes the opportunity to escape from the water and rushes upwards desperately, causing bubbles to churn.

When we drink Coke, the Coke that enters the stomach also carries a part of carbon dioxide, and because of the high temperature in the stomach, the stomach does not have time to absorb carbon dioxide, so it will be expelled from our mouth through hiccups, and we will feel very cool.

The large amount of carbon dioxide in cola is due to the high pressure used in the production process, which reduces the pressure at the moment of opening the cap and thus releases carbon dioxide from the cola.

However, this process is usually slow, and a closer look reveals that most of the bubbles are generated from the walls of the bottle, because gas production usually needs to adhere to a certain surface or certain particles, a phenomenon called nucleation.

If you zoom in a hundred times, you can see that there are many small pores on the rough surface of these sugars, and these porous structures make Mentos a good gas-producing "nucleus", and a large amount of carbon dioxide can be attached to the surface of the sugar.

Moreover, the density of Mentos is greater than that of water, and it immediately sinks to the bottom when it is added, and the gas is quickly generated at the bottom to help eject the liquid from the top.

Carbon dioxide is non-toxic, complex.

And it's easy to make. Imagine rushing into other gases, if it is nitrogen, the cola will not have a sour taste; Oxygen is hard to obtain; Others are either toxic or insoluble. Second, when carbon dioxide enters the body, it increases the osmotic pressure of blood vessels, making it easy for the body to dissipate heat and make people feel cool.

Do you know champagne, that is, it uses the carbon dioxide generated during the fermentation process to make people feel refreshed, and the same is true for cola, but the carbon dioxide is artificially added.

Because cola is a carbonated drink, carbon dioxide is added to water to produce carbonic acid, so it is called carbonated drink.

Carbonic acid is an acid produced by dissolving carbon oxide gas in water. It is very acidic, and when the temperature is slightly higher, it will decompose carbon dioxide gas. Carbonic acid is closely related to our daily lives. The soda we drink is a carbonated drink.

In the production of soda, carbon dioxide gas is dissolved in the water under pressure, and sugar, citric acid, fruit juice or flavor are added to the soda and poured into the soda bottle under pressure. When we drink soda, the soda is poured out of the bottle, the external pressure (referring to the pressure in the air and the pressure in the human body) suddenly decreases, and the solubility of carbon dioxide in the water decreases as the pressure decreases. As a result, the carbon dioxide in the soda that is drunk into the body will become a gas escaping from the water and excreted from the mouth, and this process will take away the heat in the body, which is why drinking soda feels cool.

Analysis: 1Adjust the flavor. Carbonic acid plays a role in easing the pH value of the solution in the beverage, making the flavor of various raw materials in the beverage more harmonious, setting off the aroma, and assisting the flavor of other ingredients.

2.Cool off the heat. Carbon dioxide is dissolved in the drinking branch covering, when drunk, it is discharged from the human body and takes away the amount of heat base in the body, which is conducive to the body's heat and sweating, promotes blood circulation, excites the central nervous system, and gives people a refreshing and cool feeling.

3.It plays the role of antiseptic. Carbonic acid can reduce the pH value, except for acid-resistant bacteria, other microorganisms are difficult to reproduce and survive, the presence of carbon dioxide makes the container hypoxic, many aerobic bacteria can not survive, carbon dioxide makes the container have a certain pressure, pressure can also make the microbial growth conditions break the rhythm and even die.

These characteristics can make soft drinks and sparkling wine beverages have better antiseptic ability, thereby extending the shelf life.

Carbon dioxide is added to soda to regulate flavor, bring a cool taste, and play a preservative role.

In the manufacture of soda, a large amount of carbon dioxide is dissolved in water under pressure, and then sugar, citric acid, fruit juice or flavor are added to the soda, and then poured into the soda bottle under pressure. When we drink soda, the soda is poured out of the bottle, and the external pressure suddenly decreases, and the solubility of carbon dioxide in the water decreases as the pressure decreases. The carbon dioxide in the soda is a gas that escapes from the water and is expelled from the mouth, taking away the heat from the body and making the person feel cool.

Carbonic acid can reduce the pH value, in addition to acid-resistant bacteria, other microorganisms are difficult to reproduce and survive, the presence of carbon dioxide makes the container hypoxic, many aerobic bacteria can not survive, carbon dioxide makes the container have a certain pressure, pressure can also make the microbial growth conditions destroy or even die.

Put Coca-Cola.

The ways to get carbon dioxide out are as follows, hopefully:

1.After shaking it, open the cap and leave it for a while, the carbon dioxide gas will emit out on its own, shake it a few more times and finally.

2.After the bottle cap is opened, it is placed in the sun to dry, and the carbon dioxide gas will be emitted when Coca-Cola is heated, so it can be dried more.

3.Pour it into a pot and heat it, and after Coca-Cola is heated in a pot, the carbon dioxide gas will emit out on its own, and it will be heated for a long time.

The manufacturer presses it in the production line with a pressure of several atmospheres. The principle is Henry's Law: the concentration of a dissolved gas in a liquid is proportional to the partial pressure of that gas over the liquid.

a. The gas that can extinguish the burning wood is not the same as carbon dioxide, and nitrogen can also be used, so a is wrong;

b. Carbon dioxide is a colorless and odorless gas, and there are many colorless and odorless gases, such as oxygen and nitrogen are colorless and odorless slag gases, so B is wrong;

c. The oscillating soda bottle bottle becomes deflated, and the gas that comes out is not necessarily carbon dioxide, so C is wrong;

d. Carbon dioxide can make the water of the clarified lime field stove turbid, so it is correct to use the clarified lime water to test, so D is correct

Therefore, choose D
