Normality is concentration expressed in equivalents per litre. It is useful in titration calculations. For acids, the equivalent weight is the molar mass divided by the number of acidic hydrogens (protons) that react. Dilution follows the principle that the amount of solute remains constant, so the initial normality times volume equals the final normality times volume (N₁V₁ = N₂V₂).
