Can normality change with the type of reaction?

Yes, normality can change with the type of reaction. Normality is not suitable for all situations because its value depends on an equivalence factor, which can vary depending on the chemical reaction. For instance, a 1 N solution of magnesium chloride (MgCl₂) might be 1 N for the Mg²⁺ ion but 2 N for the Cl⁻ ions. This variability makes normality less commonly used. The main reason is that normality is based on the concept of gram equivalent weight, which varies depending on how many ions participate in a reaction. Thus, normality can be inconsistent.
