Chapter 12.5, Problem 2RCF

Interpretation Introduction

Interpretation: The molar concentration for ${\text{CO}}_{\text{2}}$ in water at given temperature and pressure values should be calculated.

Concept introduction:

Henry’s law

Henry’s law states that dissolved gases in liquid are directly proportional to the partial pressure of the gas over the solution.

$\text{c = kP}$

Where,

$\text{c}$ is molar concentration of dissolved gas $\text{(mol/L)}$

$\text{k}$ is proportionality constant

$\text{P}$ is partial pressure of the gas over the solution $\text{(mol/L}\text{.atom)}$

The quantity of gas will dissolve in a solvent depends on how often the gas molecule colloid with the surface of the liquid and become attentive by the condensed phase occurs by utilizing kinetic molecular theory.

Henry’s law cannot be valid for gases at high pressure or if there is a reaction between solvent and dissolved gas.
