Formule

## How to Calculate Normality ### Formula **N = M × n** Where: - **N** = normality (equivalents/L) - **M** = molarity - **n** = equivalence factor (H+ for acids, OH- for bases, electrons for redox)

Exemple Résolu

Find the normality of 1 M H2SO4 (diprotic acid, n = 2).

  1. 01N = M × n
  2. 02N = 1 × 2
  3. 03N = 2 N

Questions Fréquentes

What is normality?

Normality (N) measures concentration in equivalents per liter. An equivalent depends on the reaction: H+ for acids, OH- for bases, or electrons for redox.

What is the n-factor?

The number of reactive units per molecule. For acids: replaceable H+ ions. For bases: OH- ions. For redox: electrons transferred.

Is normality still commonly used?

Less common now, but still used in analytical chemistry titrations and water treatment.
