Reagecon 3.8M Potassium Chloride Electrode Filling Solution (Electrolyte) Free from Silver Ion

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 3.8M Potassium Chloride remains in solution down to a lower temperature. 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. Reagecon 3.8M Potassium Chloride Electrode Filling Solution is a high quality product that fulfils all of these criteria.
