Ionic Strength Calculator
Ionic Strength of a Solution
Ionic strength measures the total concentration of ions in a solution while taking their charges into account.
The ionic strength is calculated using:
I = ½ Σ cizi2
Where:
- I = ionic strength
- ci = concentration of ion i
- zi = charge number of ion i
Concentrations are converted to mol/L before calculation. You can enter concentrations in M, mM or μM.
