A "fizz-keeper" is a small air pump that you can place on an opened soda bottle. When operated the pump is used to pressurize the air space above the soda by pumping in air from the outside. Based on Henry's law, this would be expected to the solubility of carbon dioxide in the remaining soda.

increase

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

As soda contains carbon dioxide dissolved in water.

The equation given by Henry's law is:

where,

= solubility of carbon dioxide in water

= Henry's constant

= partial pressure of carbon dioxide

Thus on increasing the pressure, the solubility of carbon dioxide also increase.
