## How to Calculate Ionic Strength

### Formula

**I = 0.5 × Sum(c_i × z_i^2)**

Ionic strength measures total charge concentration and affects activity coefficients.

Exemple Résolu

0.1 M CaCl2: 0.1 M Ca2+ and 0.2 M Cl-.

  1. I = 0.5 × (0.1 × 4 + 0.2 × 1)
  2. I = 0.5 × (0.4 + 0.2)
  3. I = 0.3 M
