Chapter 5, Problem 5D.9E

(a)

Interpretation Introduction

Interpretation:

When partial pressure of the ${\text{CO}}_{\text{2}}$ gas is doubled by the addition of more ${\text{CO}}_{\text{2}}$, the solubility of ${\text{CO}}_{\text{2}}$ has to be explained.

Concept introduction:

Henry’s law:

The solubility of a gas in a liquid is proportional to its partial pressure.

    $\begin{array}{l}{\text{Solubility = K}}_{\text{H}}\times \text{ Partial pressure}\\ \\ {\text{K}}_{\text{H}}=\text{Henry}\text{'}s\text{constant}\end{array}$

(b)

Interpretation Introduction

Interpretation:

When the total pressure of the gas above the liquid is doubled by the addition of nitrogen, the solubility of ${\text{CO}}_{\text{2}}$ has to be explained.
