Question

The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas over the solution. This statement is known as:

• A. Raoult's law
• B. Henry's law
• C. Boyle's law
• D. Charles' and Gay Lussac's Law

Answer 1

The correct option is B Henry's law

Henry's law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas over the solution.

$P_{gas}=K_H.S_{gas}$

Where, $S$ is the solubility in moles per litre
$K_H$ is henry's law constant
$P$ is the pressure in atm.
Therefore, the correct option is (B).
