Question

cdquestions Admin · Accepted Answer

The solubility of a gas in water is inversely related to its Henry's law constant (KH) . According to Henry's Law , the solubility of a gas in a liquid is given by: $C = \frac{P}{K_H}$ Where: C is the concentration (or solubility) of the gas, P is the partial pressure of the gas, K H is the Henry's law constant. A lower K H value indicates greater solubility because it means that the gas is more soluble at a given pressure. Comparison of the Henry's law constants (K H ): Methanal : K H = 0.000018 (lowest K H , highest solubility) Argon : K H = 40.3 (high K H , low solubility) Methane : K H = 0.41 (moderate K H , moderate solubility) CO₂ : K H = 1.6 (relatively low K H , good solubility but not the highest) Since methanal has the lowest K H value (0.000018), it has the maximum solubility in water at 298 K and 1 atm pressure. Thus, the correct answer is Option A: Methanal .
