Concentration by Reactive Power

Normality measures how much reactive capacity a solution carries: gram equivalents of solute per liter. For acids that means H⁺, for bases OH⁻, for redox reagents electrons transferred. This normality calculator converts grams or equivalents into N.

The n-Factor Link

Equivalent weight is molar mass divided by the n-factor — how many reactive units each molecule provides. H₂SO₄ delivers two protons, so its equivalent weight is half its molar mass, and 1 M H₂SO₄ is 2 N. Molarity × n-factor = normality, always.

Why Titrations Love It

At the equivalence point, equivalents of titrant equal equivalents of analyte — no balancing coefficients needed. That simplicity is why normality survives in analytical labs and clinical chemistry even as molarity dominates general use.
