Which law gives the relationship between the solubility of a gas in a liquid and the partial pressure of the gas?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Henry’s law
NCERT (2026-27 edition):
1.3.2 Solubility of a Gas in a Liquid – “Henry was the first to give a quantitative relation between pressure and solubility of a gas in a solvent which is known as Henry’s law. The law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of liquid or solution.”
