Chapter 13, Problem 13.87SP

Interpretation Introduction

Interpretation:

The Henry’s law constant at 298 K for ${\text{C}}_{\text{2}}{\text{F}}_{\text{4}}$ gas needs to be determined, if ${\text{C}}_{\text{2}}{\text{F}}_{\text{4}}$ gas is dissolved in water to the extent of $\text{1}\text{.01 }\times {\text{ 10}}^{\text{-3}}\text{M}$ with a partial pressure of 0.63 atm.

Concept introduction:

According to Henry's law, the amount of gas dissolved in a liquid is directly proportional to the partial pressure of the gas. The proportionality constant is known as Henry's law constant. It is mathematically represented as follows:

${\text{Concentration = K}}_{\text{H}}\text{ × Partial pressure}$

Here, concentration represents the solubility and K_H is the Henry’s constant.
