Chapter 16, Problem 181AP

Interpretation Introduction

Interpretation: The $\text{pH}$ of a solution of ${\text{CO}}_{\text{2}}$, at $38°\text{C}$, in equilibrium, is to be calculated.

Concept introduction:

$\text{pH}$ is the acidity or alkalinity of a solution, expressed on a logarithmic scale, where $\text{pH}$ equal to 7 is neutral, less than 7 is acidic, and greater than 7 is basic or alkaline.

The expression of Henry’s law is as follows:

$s=kP$

Here, $s$ is the solubility of gas in a solution, $P$ is the partial pressure of the gas in a solution at given temperature, and $k$ is Henry’s constant.
