What is the effect of pressure in the solubility of gas in liquid?

Answer 1

The higher the pressure, the more atomic collisions will take place, reducing the speed at which atoms can diffuse. Alternatively, the higher the pressure(Pressure=Force/Area), the higher the force is that is acting on the diffusing material, decreasing the diffusing materials ability to migrate to all regions of the liquid.

Answer 2

Hi,

suppose you have a closed container with liquid in the lower part of the container, and gas in the upper part under a certain pressure. at this point gas molecules are flying around the upper part randomly in all directions, some of these particles will hit the liquid surface and dive under it and get trapped because of what is called "intermolecular forces". i.e. the gas molecules become soluble in the liquid.

now as we increase the pressure the room in which the gas molecules fly around in is getting smaller and so more gas molecules will hit the liquid surface and get trapped and therefore the gas will become more soluble in water as we increase the pressure and vise versa.

i hope this helped

Answer 3

This is described by "Henry's law" which states that:

"At constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid."

Answer 4

Gases are more soluble at higher pressures.

Answer 5

s1/p1=s2/p2

Answer 6

Increased pressure = increased solibility
