Normality Calculator

Concentration measured in reactive equivalents.

Molarity scaled by reactive capacity

Normality multiplies molarity by how many 'equivalents' (reactive units, like replaceable H⁺ ions in an acid) each mole of the substance provides — sulfuric acid (H₂SO₄) has 2 equivalents per mole since it can donate 2 protons.

Why it's used in titrations

Normality is convenient in acid-base and redox titrations because 1 equivalent of acid always exactly reacts with 1 equivalent of base, regardless of how many protons each specific molecule carries.
