The solubility of gases in liquids increases with increasing pressure.
Question
The solubility of gases in liquids increases with increasing pressure.
Solution
This statement is based on Henry's Law, which states that the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Here's a step-by-step explanation:
-
When the pressure of a gas above a liquid increases, more gas molecules are forced into the liquid.
-
These gas molecules collide with the liquid surface and some of them get 'trapped' inside the liquid, which is the process of dissolving.
-
As the pressure increases, more gas molecules are forced into the liquid, hence the solubility of the gas in the liquid increases.
-
Conversely, if the pressure is decreased, fewer gas molecules are forced into the liquid, and some of the gas molecules already in the liquid will escape back into the gas phase, hence the solubility decreases.
-
Therefore, the solubility of gases in liquids increases with increasing pressure.
