What it calculates

The “Ionic strength” calculator computes Ionic strength in mol/L from 2 parameters: concentration (mol/L), charge.

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters Concentration = 0.1 mol/L, Charge = 1 the result is 0.05 mol/L (½·Σc·z²).
