Question

According to Henry's law, the solubility of a gas in a given volume of liquid increases with increase in :

• A. temperature
• B. pressure
• C. both A and B
• D. none of the above

Answer 1

Answer: (B)

pressure

According to Henry's law, $S=KP$
$S$ is the solubility in moles per liter
$K$ is the henry's law constant
$P$ is the pressure in atm.

Thus, when pressure increases, the solubility of the gas in a given volume of liquid increases. But when the temperature increases, the solubility of the gas in a given volume of liquid decreases.

Option B is correct.
