About Ionic Strength
Ionic strength (I) is a measure of the concentration of ions in a solution. It's calculated using the formula:
I = ½ Σ(ci × zi²)
Where:
- I = Ionic strength (mol/L)
- ci = Molar concentration of ion i (mol/L)
- zi = Charge number of ion i
Ionic strength affects the activity coefficients of ions in solution and is important in understanding solution behavior, especially in biological systems and chemical equilibria.
