Chapter 10, Problem 60E

Interpretation Introduction

Interpretation:

The Henry’s law constant for air is to be calculated.

Concept introduction:

The amount of gas dissolvedin a given volume of liquid is directly proportional to its partial pressure in the gas phase at constant temperature is stated by the Henry’s law. The relationship between concentration of gas and the partial pressure of the gas is given by Henry’s law. The equation for the same is,

${\text{C}}_{\text{gas}}={\text{k}}_{\text{H}}\cdot {\text{P}}_{\text{gas}}$

To determine:

If the ${\text{k}}_{\text{H}}$ value of air is approximately equal to the sum of ${\text{k}}_{\text{H}}$ values of ${\text{N}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$ .
