Which of the following laws describes the relationship between solubility of gas in a liquid and the pressure of the gas over the solution at a given temperature?
Options
- ARaoult's Law
- BHenry's Law
- CDalton's Law
- DGay-Lussac's Law
Correct answer
B. Henry's Law
Step-by-step solution
Henry's Law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas present above the surface of liquid or solution. Raoult's Law relates the vapor pressure of a solvent to its mole fraction in a solution. Dalton's Law states that the total pressure of a mixture of non-reacting gases is equal to the sum of their partial pressures. Gay-Lussac's Law states that the pressure of a fixed mass of gas is directly proportional to its absolute te
