Question

Lowering of vapor pressure Δ P 1 ​ of an aqueous solution of acid HA₁ and Δ P 2 ​ of an aqueous solution of acid HA₂ are related as Δ P 1 ​ > Δ P 2 ​ . The correct relation is (assuming the same concentration for both acids):

TestHub · Accepted Answer

Lowering, Δ P ∝ 'a' number of solute particles. Hence, HA 1 ​ is stronger acid than HA 2 ​ ( Given Δ P 1 ​ > Δ P 2 ​ ) and pK a 1 ​ ​ < pK a 2 ​ ​ .
