Frequently Asked Questions

What is normality?
Normality (N) is the number of gram equivalents of solute per liter of solution. It equals molarity multiplied by the n-factor (number of H⁺, OH⁻, or electrons exchanged per molecule).
When should I use normality instead of molarity?
Normality is preferred in acid-base titrations and redox reactions because it directly accounts for the reactive capacity of each molecule, simplifying stoichiometric calculations.
