Chapter 14, Problem 105IAE

Interpretation Introduction

Interpretation:

Volume percent of N₂ and O₂ gases dissolved in water should be estimated.

Concept introduction:

Henry’s law

$\begin{array}{l}\text{}{\text{C = K}}_H\times {\text{P}}_{gas}\\ \text{C = solubility of gas}\\ {\text{K}}_H=\text{ Henry's law constant}\\ {\text{P}}_{gas}\text{ = partial pressure of the the gas above the solution}\\ \\ \text{Partial pressure of a gas = Total pressure }\times \text{ mole fraction of the gas}\end{array}$

When the temperature remains unchanged, Henry’s law constant remains as a constant.
