Given below are two statements: Statement I: The Henry's law constant K_H is constant with respect to variations in solution's concentration over the range for which the solutions is ideally dilute. Statement II: K_H does not differ for the same solute in different solvents. In the light of the above statements, choose the correct answer from the options. (1) Statement I is false but Statement II is true. (2) Statement I is true but Statement II is false. (3) Both Statement I and Statement II are true. (4) Both Statement I and Statement II are false.

1. Statement I is false but Statement II is true.
2. Statement I is true but Statement II is false.
3. Both Statement I and Statement II are true.
4. Both Statement I and Statement II are false.

Correct answer: Statement I is true but Statement II is false.

Solution

Statement I is correct because Henry's law constant remains constant for ideal dilute solutions, indicating a direct proportionality between the concentration of the gas and its partial pressure. However, Statement II is incorrect as K_H can vary significantly for the same solute in different solvents due to differences in solvent-solute interactions.
