Question

Assertion : The solubility of a gas in a liquid increases with increase of pressure.
Reason : The solubility of a gas in a liquid is directly proportional to the pressure of the gas.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

This is according to Henry’s law which states that the solubility of a gas in given volume of a liquid at a particular temperature is directly proportional to the pressure of gas above the liquid. m $\infty$ p, m = kp where k = Henry’s constant.
