Chapter 13, Problem 30QRT

Interpretation Introduction

Interpretation:

The concentration of ${\text{O}}_{\text{2}}\left(\text{in}\text{grams}\text{per}\text{liter}\right)$ that dissolves in water at ${\text{37}}^{\text{o}}\text{C}$ has to be calculated.

Concept introduction:

Henry’s law: The quantitative relationship between gas pressure and solubility: the solubility of a gas $\left({\text{S}}_{\text{gas}}\right)$ is directly proportional to the partial pressure of the gas $\left({\text{P}}_{\text{gas}}\right)$,

  ${\text{S}}_{\text{gas}}\text{=}{\text{k}}_{\text{H}}\text{×}{\text{P}}_{\text{gas}}$.

Where,

  ${\text{S}}_{\text{gas}}$ is the solubility of gas.

  ${\text{k}}_{\text{H}}$ is Henry’s law constant.

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