Chapter 16, Problem 109E

Interpretation Introduction

Interpretation:

The normality of sodium carbonate of volume $\text{25}\text{.0-mL}$ titrated with $\text{39}\text{.8 mL}$ of $\text{0}\text{.405 N}$ of sulfuric acid is to be calculated.

Concept introduction:

An acid base reaction is one of the types of reaction which is known as neutralization reaction. Normality is a unit of concentration use to express concentration of solutions. n factor of any species is defined in different way depending upon the type of reaction. In an acid base reaction n-factor is defined as the number of replaceable ${\text{H}}^{\text{+}}$ of an acid and for a base it is the total charge present on a species after removing all metal ions. Equation which equates the equivalents of an acid and a base is given below.

$\underset{\text{equivalents of acid }}{\underbrace{{\text{n}}_{\text{1}}{\text{M}}_{\text{1}}{\text{V}}_1}}=\underset{\text{equivalents of base}}{\underbrace{{\text{n}}_{\text{2}}{\text{M}}_{\text{2}}{\text{V}}_{\text{2}}}}$
