Chapter 12, Problem 12.48QP

Interpretation Introduction

Interpretation:

Solubility of Nitrogen gas in water at $4.79\text{ atm}$ pressure has to be calculated.

Concept Introduction:

Solubility of a gas in liquid is explained by Henry’s law which states –

“At a constant temperature, the amount of a gas dissolved in a given volume of liquid is directly proportional to the partial pressure of the gas that is in equilibrium with the liquid.”

It is expressed as,

$S\alpha P$

Where,

$\begin{array}{l}S\text{ = Solubility}\\ \text{P = Partial pressure}\end{array}$

Introducing proportionality constant,

$S=k_{H}P$

Where,

$k_H$ is Henry’s constant.
