Tuzlar aralashmasi suvda eriganida hosil bo‘lgan eritmada 1,5 mol SO₄²⁻, x mol Na⁺, 0,25 mol Mg²⁺, 0,65 mol NO₃⁻ hamda 1 mol Fe³⁺ kationlari mavjud. Ushbu eritmadagi natriy ionining miqdorini (mol) aniqlang.

Elektroneytrallik: Σ(+) = Σ(−). x + 2·0,25 + 3·1 = 2·1,5 + 0,65 → x + 3,5 = 3,65 → x = 0,15 mol.
