Websolution may also have some effect. The ionic strength is defined as half of the total sum of the concentration (ci) of every ionic species (i) in the solution times the square of its charge (zi); i.e. I = 0.5S(cizi2). For example, the ionic strength of a 0.1 M solution of CaCl2is 0.5 x (0.1 x 22+ 0.2 x 12) = 0.3 M. At http://electrochemsci.org/papers/vol7/71212404.pdf
