Concentrated or saturated Potassium Chloride (KCl) is the optimal electrolyte and filling solution for potentiometric titrations, direct pH measurement, redox or ion measurement where silver/silver chloride or calomel reference electrodes are used. However, saturated KCl is only sparingly soluble below 20°C, so if measurements below this temperature are to be carried out 4M Potassium Chloride remains in solution and confers an advantage over saturated potassium chloride. - A good electrolyte must fulfil a number of conditions. The equitransference of the cation/anion combination should be as close as possible to being equimobile, have constant chloride activity, be of high electrical conductance and be as non-chemically reactive as possible.
