Chapter 11, Problem 11.4VP

Interpretation Introduction

Interpretation: The given graph shows the variation in solubility of nitrogen, oxygen and helium gases with pressure. The gas which gives rise to each line in the given Figure P11.4 is to be identified.

Concept introduction: Henry’s law states that the solubility of a gas in a liquid is directly proportional to the pressure of that gas above the surface of the solution.

$\begin{array}{l}{S}_{\text{g}}=k_{\text{H}}{P}_{\text{g}}\\ k_{\text{H}}=\frac{S_{\text{g}}}{P_{\text{g}}}\end{array}$

To determine: The gas which gives rise to each line in the given Figure P11.4.
