Question

The relationship between solubility of a gas in a liquid at constant temperature and external pressure is:

• A. \( S \propto \frac{1}{P} \)
• B. \( S \propto P \)
• C. \( S \propto P^2 \)
• D. None of the above

Hint:

Henry’s law states that the higher the pressure of a gas, the greater its solubility in a liquid at constant temperature.

Answer 1

The Correct Option is D

According to Henry’s law, the solubility of a gas (\( S \)) in a liquid is directly proportional to the external pressure (\( P \)) at a constant temperature.
Conclusion: The relationship is \( S \propto P \).
