Interpretation Introduction

Interpretation:

The pressure of ${\text{O}}_{\text{2}}$ required to forman aqueous solution of $3.4\times {10}^{-2}M$ by concentration, at 25°C, and Henry’s law constantareto be calculated.

Concept introduction:

William Henry has given a quantitative relation of pressure and solubility of a gas in a solvent, known as Henry’s law.

According to this law, the solubility of a gas is in direct proportionality to the partial pressure of the gas present above the surface of the liquid or the solution.

Mathematically, it can be expressed as follows:

$c=kP$

Here, $c$ is the molar concentration of the dissolved gas, $k$ is Henry’s law constant, and $P$ is the pressure of the gas over the solution.
