Descripción
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 as non-chemically reactive as possible.
Potassium Chloride (KCl) fulfils all of these conditions to a greater or lesser extent, and is the filling solution of choice in either potentiometric titrations or direct pH, redox or ion measurements where silver/silver chloride or calomel reference electrodes are used. 3M KCl is appropriate where the working temperature is at least 20°C.
