How does pressure affect the solubility of a gases?

Answer 1

The solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

Answer 2

At high pressure the solubility increase.

Answer 3

The solubility of gases in liquids is greatly affected by pressure.It is directly proportional to pressure i.e. increasing pressure increases solubility of gas in water.

The relationship between solubility of gas and pressure was given by Henry in the form of Henry's law which is stated as follows:-

"The partial pressure of the gas in vapour phase is proportional to mole fraction of the gas in the solution"

Answer 4

C=k*P

where C=solubility

k=temperature dependent constant

p=partial pressure

This is Henry`s Law: the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

Think of a bottle of cola.It is bottled under pressure so that it contains a high dissolved carbon dioxide in the liquid.As one opens the bottle, the pressure of the gas above the liquid drops and carbon dioxide starts to bubble off.

Less pressure,less solubility.

Answer 5

Solubility is direct proportional to pressure

Answer 6

The solubility of gases increase with increase in pressure.
