Chapter 2, Problem 2.CE

Interpretation Introduction

Interpretation:

The concentration of Potassium permanganate ${\text{KMnO}}_{\text{4}}$ at $\text{16°C}$ should be calculated.

Concept introduction:

Correction for thermal expansion:

The temperature changes are make a changes in concentration (molarity) of the solutions and this concentration change at given temperature is calculated by mathematical method is known as correction for thermal expansion.

$\frac{\text{c'}}{\text{d'}}\text{ =}\frac{\text{c}}{\text{d}}$

Where,

$\text{c'}$ is concentration of solution at temperature.

$\text{d'}$ is density of solution at temperature.

$\text{c}$ is concentration of solution at apply temperature.

$\text{d}$ is the density of solution at apply temperature.
