Where does the gas in Coke come from? What gas is in Coke

First open the cap of the half-drunk Coke, then squeeze the bottle with your hands to squeeze out the gas inside, and then immediately close the cap, so that the bottle becomes very flat, there is no gas in it, and when you open it next time, it will still taste original, and the gas will not go away and be very full.

Sealing problems, carbon dioxide is gone. Of course, it tastes like sugar water, because cola is sugar water with a lot of ingredients added to it.

The lid has been loosened by others, and there are some people who are more bt who will do this, and Yam will carefully check some bottle caps every time he buys carbonated drinks.

Fake it! Take a good look at the production date! It's best to call the customer service to make sure that what you buy is genuine! If it's true, go and return it! If it's fake, you should go back too.

It's expired, huh.

Poor sealing (or yes).

It's expired, or it's not well sealed.

If you are not sure if you don't drink it, ask the seller why this is the case.

Coke contains carbon dioxide gas, which can generally be prepared by calcining limestone at high temperature or by the reaction of limestone and dilute hydrochloric acid, which is mainly used in refrigerating perishable food (solid), as a refrigerant (liquid), making carbonized soft drinks (gaseous) and solvents for homogeneous reaction (supercritical state).

Cola, which refers to a sweet, caffeinated but non-alcoholic carbonated drink, is very popular. The main flavors of cola include vanilla, cinnamon, lemon and so on. The name comes from one of the early materials of Coke:

The most well-known cola brands are Coca-Cola and Pepsi. Drinking Coke is a consumption behavior that is no different from drinking other beverages. However, the cola culture, its connotation is too rich, far beyond"Drink a drink"category.

Sprite and Coke are two carbonated drinks that we often drink. It is named because it contains carbonic acid. Chemistry books say that carbon dioxide dissolves in water and then forms carbonic acid.

This process is a reversible one. In other words, carbon dioxide can be converted into carbonic acid with water, and carbonic acid can also be converted into carbon dioxide and water. Carbonic acid is an unstable substance that can easily decompose under conditions such as heating, depressurization, and **.

The gas inside Coke is the carbon dioxide produced by the decomposition of carbonic acid inside.

When cola is produced, carbon dioxide is dissolved in water under pressure, and after filling, a small amount of carbon dioxide will overflow, making the bottle very hard. In this way, the air pressure inside the bottle is higher than the outside atmospheric pressure. When we open the soda bottle, the drop in air pressure also causes the carbon dioxide that was originally dissolved in the water under pressure to decompose, and the gas overflows, and the bottle is not fully opened, and the friction of the air flow will produce a snorting sound of exhaust.

When we buy Coke, we generally buy refrigerated Coke, and these refrigerated Cokes have a temperature difference with the outside world after they are taken out of the freezer. The rise in temperature will also cause the carbonic acid in the bottle to decompose. There are also friends who like to take a few sips and shake the lid, and the bottle will harden again.

This is because the ** causes carbonic acid to decompose carbon dioxide, and the air pressure is greater than the outside atmospheric pressure caused by the expansion of the bottle.

A large number of teenagers like to drink carbonated drinks, in fact, carbonated drinks are not conducive to physical health, long-term drinking will corrode teeth, affect the absorption of calcium by the stomach and intestines, damage the gastric mucosa, contain sweeteners and a lot of calories, the accumulation of calories is also easy to cause obesity. Carbonated drinks are the more you drink, the thirstier you get. It's okay to taste it when you think about it, but it's better to drink less anyway.

When you are thirsty, drink cool and white, quenching your thirst is good for your body.

The main ingredient of bubbles in cola is carbon dioxide, commonly known as "carbon acid"!

In addition, there is a small amount of air in Coke, and the main components of air are nitrogen and oxygen, so there must be these two gases in Coke!

Finally, there is also a certain amount of water vapor above the surface of the Coke!
