The formula
normality = molarity × equivalents per mole equivalent weight = molar mass ÷ equivalents per mole
At the equivalence point of a titration, N₁V₁ = N₂V₂.
What to watch out for
Count only the protons, hydroxide ions or electrons that take part in the reaction you are using.
Frequently Asked Questions
How do I convert molarity to normality?
Multiply by equivalents per mole. 0.1 mol/L citric acid reacting all three protons is 0.3 eq/L.
Is normality the same as molarity?
Only when there is one equivalent per mole, as with hydrochloric acid or sodium hydroxide.
