Chapter 21, Problem 41R

To determine

To Choose: The correct option.

Answer to Problem 41R

Correct option is B.

Explanation of Solution

Introduction:

Gases are expected to have increase in solubility as the pressure increases.

As soon as the pressure is increased, the gas molecules which are above the liquid surface are being "forced" to move into the solution. As a result, there is less number of gas molecules above the surface. Hence, the more number of gas molecules get dissolved in the liquid.

According to Henry's Law, the amount of a gas dissolved in a liquid is directly related to the pressure of that gas.

Example: All carbonated beverages are closed to increase solubility of the carbon dioxide in the drink.

Conclusion:

Thus, pressure can be increased to make a gas more soluble in a liquid.
