How does a soft drink become fizzy?

Answer 1

Answerit is carbonated AnswerThe carbon bubbles in the soda move around and fizz.

The fizz that bubbles up when you crack open a can of soda is carbon dioxide gas. Soft drink manufacturers add this tingling froth by forcing carbon dioxide and water into your soda at high pressures-up to 1,200 pounds per square inch. An unopened soda can is virtually bubble-free because the pressure inside the can keeps the carbon dioxide dissolved in the liquid.

When you crack open the can, you release the pressure and allow the gas bubbles to wiggle free from the liquid and rise to the surface. This requires energy because in order for the gas to break free from the liquid it has to overcome the force holding the liquid together.

sorry its not 1200 psi actually about 87-100 psi and co2 can only be forced into water after it has been evacuated of all oxygen, pop shouldn't be frothy unless it has been shaken in a pressurised container, if pop feels frothy to drink it has been canned or bottled wrong, this is what is known as "fobbing" in the industry, if a pop has been made correctly is should really appear flat with the occasional bubbles.

some pop is actually flat because it has been dosed with liquid nitrogen.

Answer 2

CO2 is dissolved under pressure in the liquid, and when the pressure is released the amount that can be dissolved is reduced, so it escapes as gaseous CO2. This generally results in the bubbles that you see and why there is an initial fizz when you first open the bottle. The higher the pressure, the more CO2 can be dissolved, equally the colder the water, the more can be dissolved.

Dissolved CO2 also creates a weak acid, which can change the taste of the beverage.

Answer 3

A soft drink becomes fizzy through the process of carbonation. Carbonation is the process of dissolving carbon dioxide gas in the beverage under pressure. When the beverage is opened, the pressure is released, causing the carbon dioxide to come out of solution in the form of bubbles, creating the fizzy sensation.

Answer 4

no the amount of carbonation in the water does

Answer 5

Yep it does ch3O is carbonic acid. however the bond isn't good so when it fizzes it seperates back into H2O and CO2

Answer 6

Carbon dioxide (CO2) contains only carbon and oxygen, and it makes soda fizz. Carbohydrates contain those two elements and also hydrogen.
