Question

An aqueous solution is 1.00 molal in KI. Which change will cause the vapour pressure of the solution to increase? (A) Addition of water (B) Addition of NaCl (C) Addition of Na2SO4 (D) Addition of 1.00 molal KI

Tardigrade Admin · Accepted Answer

With addition of water, concentration decreases thus vapour pressure increases
