was prepared by dissolving palladium (II) chloride in water (to which
0.1 ml of concentrated hydrochloric acid has been added). The mixture
was then warmed in a water bath to ensure complete dissolution.
The ionic strength (l) of the final solution for determination
was kept constant at 0.2 M, by the addition of a 2 M potassium
chloride solution. Britton Robinson buffer was used to adjust the
