Question:
Statement-I: K$_h$ for ideal dilute solution does not change with varying the concentration of solute.
Statement-II: K$_h$ for solution having same gas solute is independent of nature of solvent?
Statement-I: K$_h$ for ideal dilute solution does not change with varying the concentration of solute.
Statement-II: K$_h$ for solution having same gas solute is independent of nature of solvent?
Statement-II: K$_h$ for solution having same gas solute is independent of nature of solvent?
Show Hint
Henry's law constant (K$_h$) is dependent on the nature of both the solvent and the solute, and temperature also plays a key role.

The Correct Option is B
Solution and Explanation
Step 1: Analyzing Statement-I.
Statement-I is correct. Henry's law constant (K$_h$) for an ideal dilute solution is independent of the concentration of solute, as long as the gas behaves ideally. This constant only depends on temperature and the nature of the solute and solvent.
Step 2: Analyzing Statement-II.
Statement-II is incorrect. K$_h$ depends on both the nature of the gas and the solvent. It is not independent of the solvent's nature. For example, different solvents will dissolve the same gas to different extents, affecting the value of K$_h$.
Step 3: Conclusion.
Thus, Statement-I is correct, and Statement-II is incorrect, making option (2) the correct answer.
