What does Henry's Law state regarding the solubility of a gas in a liquid at constant temperature?

Answer and explanation

Correct answer: C. Mass of dissolved gas is directly proportional to the partial pressure of the gas above the liquid

  1. Step 1: William Henry formulated that gas dissolves until dynamic equilibrium between gaseous and dissolved states is reached. Step 2. C = k_H P: the amount of gas dissolved is directly proportional to its partial pressure above the solution. Answer: Mass of dissolved gas is directly proportional to the partial pressure of the gas above the liquid. Why not the others:* Gas solubility in liquids decreases with increasing temperature; inverse proportionality is false; chemical identities have different Henry's constants.
