What are the differences between normality and molarity?

Question

Accepted Answer

Basis of differentiation

Normality

Molarity

Definition

Normality measures the number of gram equivalents of a solute per liter of solution

Molarity measures the number of moles of a solute per liter of solution

Units

N or eq L^-1

M or Moles L^-1

Function

It is used in measuring the gram equivalent in relation to the total volume of the solution

It is used to determine the ratio of the number of moles to the total volume of the solution

Preferred use

General laboratory use, most common for preparing solutions

Titration calculations, reactions where equivalence is key
