Applications. Commercial reference electrodes consist of a plastic tube electrode body. The electrode is a silver wire that is coated with a thin layer of silver chloride, either physically by dipping the wire in molten silver chloride, chemically by electroplating the wire in concentrated hydrochloric acid or electrochemically by oxidising the silver in a chloride solution.

From the solubility, the Cu(s) is, naturally, the reducing agent in this case, as it causes Ag+ to gain electrons. As a summary, here are the steps to follow to balance a redox equation in =E0-0.05916(log[Cl-]) = 0.281 V. =3.5 M. =0.1M. If pH in sample is 7.00, and pH inside is 1.00. What is cell potential?
