Question

The value of Henry's constant K$_H$ is:

• A. greater for gases with higher solubility
• B. greater for gases with lower solubility
• C. constant for all gases
• D. not related to the solubility of gases

Hint:

Remember, Henry's constant increases as the solubility of the gas decreases. It is a measure of the gas’s tendency to escape from the solution.

Answer 1

The Correct Option is B

The principle of Henry's law asserts that, at a fixed temperature, the quantity of gas dissolving in a liquid correlates directly with the gas's partial pressure over the liquid. Henry's constant (K$_H$) exhibits an inverse relationship with gas solubility; a reduction in solubility leads to an increase in Henry's constant, thereby validating option (B).
