Which chemical law states that the mass of a gas dissolved in a given volume of solvent at constant temperature is directly proportional to the partial pressure of the gas in equilibrium with the solution?

💡 Solution & Explanation

Henry's Law states that at a constant temperature, the concentration of a dissolved gas in a liquid is directly proportional to the partial pressure of that gas in equilibrium with the liquid. Raoult's Law and Dalton's Law govern vapor pressures of ideal solutions and partial pressures of gas mixtures respectively, rather than gas-liquid solubility dynamics. This chemical principle explains why carbon dioxide remains dissolved under high pressure inside sealed beverage containers until the cap is removed. Scuba divers must account for Henry's Law to prevent decompression sickness during deep-sea ascents.
