The solubility of Ar in water at 25 °C is 1.6 × 10^-³M when the pressure of the Ar above the solution is 1.0 atm. The solubility of Ar at a pressure of 2.5 atm is M. A) 4.0 × 10^-³ B) 7.5 × 10^-² C) 1.6 × 10^-³ D) 6.4 × 10^-⁴ E) 1.6 × 10³

Question

Quizplus · Accepted Answer

According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the pressure of the gas above the liquid. Therefore, if the pressure increases from 1.0 atm to 2.5 atm, the solubility will increase by the same factor. Thus, 1.6 × 10^-3 M × 2.5 = 4.0 × 10^-3 M.
