WebThe ionic strength of a solution is a function of the concentration of all ions present in a solution: (5) I = 1 2 ∑ i z i 2 c i. Here, c i and z i are the molar concentration and the charge of ion i. The sum is taken over all ions in the solution. Due to the square of z i, multivalent ions contribute particularly strongly to the ionic strength.
