Solutions Part 2

Concept:Henry's law states that at constant temperature, the partial pressure of a gas above a liquid is directly proportional to its mole fraction in the liquid. The proportionality constant $K_H$ depends on the solute and the solvent.Explanation:For an ideally dilute solution, Henry's law is obeyed as $p = K_H x$. At a fixed temperature, $K_H$ remains constant over the concentration range where the solution behaves ideally (i.e., dilute enough). Therefore, Statement I is true.The value of $K_H$ depends on the nature of the gas (solute), the nature of the solvent, and the temperature. Thus, for the same solute, $K_H$ can be different in different solvents. Hence, Statement II is false.Answer:Option B: Statement I is true but Statement II is false.
