Chapter 13, Problem 13.30QP

Interpretation Introduction

Interpretation:

Two exceptions of Henry’s law has to be given.

Concept Introduction:

Henry’s law

At constant temperature, amount of dissolved gas and volume of liquid proportional to the partial pressure of that gas in equilibrium with that liquid. This law applies most precisely for dilute solutions of a gas that does not react or dissociate with the solvent.

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 $\text{(mol/L}\text{.atom)}$
