Chapter 10, Problem 23Q

Interpretation Introduction

Interpretation: The difference in two concentrations units are to be explained along with the equality in normality and molarity.

Concept Introduction:

The equivalent concentration of solution otherwise called as Normality is the measure of concentration in terms of the gram equivalent weight per litre of solution. The role of solute in the reaction is used for the calculation of normality of a solution. Normality can be given by the formula,

$\text{Normality=}\frac{\text{Number}\text{of}\text{gram}\text{equivalent}\text{of}\text{solute}}{\text{Volume}\text{of}\text{solution}\text{in}\text{litre}}$

The concentration of solution can be defined in terms of Molarity, as moles of solute (in grams) to the volume of solution (in litre). Molarity can be given by the formula,

$\text{Molarity(M)=}\frac{\text{Moles}\text{of}\text{solute(in}\text{g)}}{\text{Volume}\text{of}\text{solution(in}\text{L)}}$
