Ionic Strength Calculator (I) — Frequently Asked Questions
Q1 Why does MgSO4 have 4 times the ionic strength of NaCl at the same molarity? ▾
Ionic strength scales with the SQUARE of ion charge. In MgSO4, both Mg²⁺ and SO4²⁻ have charges of ±2 (2² = 4), yielding 0.5 × (4 + 4) = 4M, whereas for NaCl (1² = 1), 0.5 × (1 + 1) = 1M.
