Interpretation Introduction

Interpretation:

The equivalent mass of the acid if $\text{15}\text{.6}\text{mL}$ of $\text{0}\text{.562}\text{N}$ sodium hydroxide is required to titrate a solution prepared by dissolving $\text{0}\text{.631}\text{g}$ of an unknown acid is to be predicted.

Concept introduction:

Normality is defined as the number of equivalents of solute per unit volume of the solution. Equivalent mass is the mass of the compound per equivalent. One equivalent of any substance means it would react with or supply one mole of electron or protons in a reaction.
