Interpretation Introduction

Interpretation:

The solubility of ${\text{N}}_2$ in water at ${25}^{°}\text{C}$ and $1\text{}\text{atm}$ is to be determined.

Concept introduction:

Henry’s law gives the quantitative relationship between the pressure of the gas and its solubility. It states that the amount of gas dissolved in a liquid is proportional to the partial pressure of the gas. Higher the partial pressure of the gas, more will be its solubility and vice-versa.

The formula to calculate the solubility of gases according to Henry’s law is as follows:

$S_{\text{gas}}=\left(k_{\text{H}}\right)\left(P_{\text{gas}}\right)$ (1)

Here, $S_{\text{gas}}$ is the solubility of the gas.

$k_{\text{H}}$ is Henry’s constant.

$P_{\text{gas}}$ is the partial pressure of the gas.
