Question

The relation between solubility of a gas in liquid at constant temperature and external pressure is stated by which law?

विकल्प

• Raoult's law 

• Van't Hoff - Boyle's law

• Van't Hoff - Charles' law 

• Henry's law

Answer 1

Henry's law

Explanation:

The relationship between solubility of a gas in liquid at constant temperature and external pressure is given by Henry's law. x ∝ Partial pressure of the gas, p

p = K_H x

Here, K_H = Henry's law constant

More the value of K_H, lower is the solubility of gas.
