The only incorrect statement regarding Henry’s law for a gas dissolving in water, is — Solutions and Colligative Properties Chemistry Question

💡 Solution & Explanation

The value of Henry's constant ($K_H$) depends on the nature of the gas. Generally, less soluble gases have higher $K_H$ values. Hydrogen is less soluble than oxygen in water, so $\text{H}_2$ has a higher $K_H$ than $\text{O}_2$. Hence statement (a) is incorrect. Therefore, correct answer is A.
