Why do Carbonated Beverages become flat?

Answer 1

The 'fizzyness' in fizzy drinks is carbonic acid, or H2CO3. It is pumped into the drink at high pressure but it is very unstable. When opening the bottle, the pressure is released and the carbonic acid falls apart in carbon dioxide and water. In chemical terms:

H2CO3 -> CO2 + H2O

The carbon dioxide can be seen as the little bubbles floating upwards in the drink. It is also the reason for the tickely feeling in your mouth. When the fizzy carbon dioxide is gone, and the drink is diluted by the formed water, your drink is flat.

Answer 2

It loses carbon dioxide into the atmosphere.

Answer 3

It doesn't have gas as regular soda's have.

Answer 4

Soda pop will get flat when the carbonation is gone and when this occurs the soda then becomes what is known as flat.

Answer 5

Atoms are further apart when heated, thus carbonation escapes more freely. The hotter something is the futher the atoms are.

Answer 6

it goes flat because it looses carbon dioxide to the atmosphere.

Answer 7

because the pressurised carbon dioxide gas is released

Answer 8

Carbonated Beverages have carbon dioxide put into. They become flat when the CO2 escapes.

Answer 9

many would agree that it goes flat because it losses its fizzles because it goes past its expiration date
