Ionic strength ( or ) is a measure of the total concentration of ions in a solution, defined by where is the charge of ionic species and is its concentration.
this is a measure of the effective concentration of ions in solution. It is calculated according to the following formula: Ionic strength = 1 /2 CxZ^2 (where: Cx = the concentration of ion x; Zx = the charge of ion x). The ionic strength determines the activity coefficient of each ion in the solution. Conductivity measurements give an estimate of ionic strength.
expresses the effect of the charge of the ions in a solution. It is determined by the concentration and charge of each of the different ions present in a solution.
The weight concentration of ions in solution, computed by multiplying the concentration of each ion in solution (C) by the corresponding square of the charge on the ion (Z) summing this product for all ions in solution and dividing by 2:ionic strength - 1/2 _ Z2 C.
