Salt will upset the chemical structure and energy balance of cola, making it release too much carbon dioxide, which will cause cola to spew out of the bottle like a fountain. Salt dissolves in water, which destroys the dissolution balance of carbon dioxide originally dissolved in cola. When the concentration of carbon dioxide is too high, it will precipitate and become gaseous.

That is, bubble salting-out refers to the process of adding inorganic salts to the solution to reduce the solubility of a substance and precipitate it. Adding salt to cola will produce a lot of bubbles, which is a salting-out phenomenon. The reason is that after salt is dissolved in cola, the concentration of the solution increases, which leads to the dissolution of carbon dioxide in cola.

Extended data:

Coke, also known as soda and happy fat house water, refers to a very popular carbonated drink with sweetness, caffeine and no alcohol, mainly with vanilla, cinnamon and lemon flavors. The main raw materials of cola are water, carbon dioxide and carbohydrates, which mainly contain nutrients such as sodium, energy, carbonic acid and carbohydrates.

At present, the well-known cola brands are Coca-Cola and Pepsi. It is known that cola contains a large amount of carbon dioxide gas. After the carbon dioxide gas enters the human body, it will take away the heat of the human body through the burping of the gas from the stomach, thus achieving the purpose of heat dissipation.

This is why people like to drink iced coke in summer. Coke will slowly release carbon dioxide under normal conditions, but after adding salt, it will quickly vaporize and produce more carbon dioxide. The reason why cola will erupt with salt is that there is a lot of carbon dioxide gas in cola, which will slowly release carbon dioxide when there is no external interference.

However, when a small amount of finely divided solid powder salt is added, coke will produce many gasification centers, thus accelerating the release of carbon dioxide. Therefore, cola will erupt.

Salt will upset the chemical structure and energy balance of cola, making it release too much carbon dioxide, which will cause cola to spew out of the bottle like a fountain. Salt dissolves in water, which destroys the dissolution balance of carbon dioxide originally dissolved in cola.

Salting out refers to the process of adding inorganic salts to the solution to reduce the solubility of substances and make them precipitate. Adding cola salt will produce many bubbles, which is the salting-out phenomenon. The reason is that after salt is dissolved in coke, the solution concentration increases, which leads to the decrease of the solubility of carbon dioxide in coke, and thus a large amount of carbon dioxide overflows. The salting-out phenomenon does not produce new substances, so it belongs to physical changes rather than chemical changes.
