Chapter 13.3, Problem 3Q

Interpretation Introduction

Interpretation: The solubility of $C{O}_2$ in water at ${25}^{0}C$ has to be calculated if the pressure of the gas is $\text{3}{\text{.7×10}}^{\text{-4}}\text{bar}$.

Concept introduction:

Henry’s law: The solubility of a gas in liquid is directly proportional to the gas pressure.

$\begin{array}{l}{\text{S}}_{\text{g}}{\text{= k}}_{\text{H}}{\text{P}}_{\text{g}}\text{,}\\ \text{where,}{\text{S}}_{\text{g}}\text{is}\text{the}\text{gas}\text{solubility}\text{(in}\text{mol/kg)}\\ {\text{k}}_{\text{H}}\text{is Henry's constant }\\ {\text{P}}_{\text{g}}\text{ is the partial pressure of the gaseous solute}\text{.}\end{array}$
