Limits in Using Normality
While normality is a useful concept in certain types of chemical analysis, it has several limitations which are mentioned below:
- Normality is dependent on the stoichiometry of the reaction.
- The number of equivalents per mole of solute can vary depending on the specific chemical reaction or species involved.
- Normality is primarily used in acid-base and redox reactions where the stoichiometry involves the transfer of protons, ions, or electrons. It may not be applicable or meaningful for other types of reactions, such as precipitation reactions or complexation reactions.
- Normality does not account for the presence of other species in solution that may interfere with the reaction or affect the accuracy of the measurement.
- Determining the exact number of equivalents per mole of solute can be challenging, especially for complex reactions or mixtures of species.

How to Calculate Normality of a Solution?
Normality is calculated by dividing the number of Equivalent Weights of a solute by the volume of the solution in liters. The formula for calculating Normality is N = number of Equivalent weights of solute/volume of Solution in liters , where N is normality. Each substance has different equivalent wrights. In this article we are going to learn what is normality, how to calculate normality and some sample problem on normality concept.
