Final answer:
The silver chloride electrode (Ag/AgCl) converts the potential in an aqueous solution to the wire by acting as a reference electrode and undergoing a redox reaction. The silver metal in the electrode is oxidized to form silver ions, while chloride ions in the solution are reduced to form solid silver chloride.
Step-by-step explanation:
The silver chloride electrode (Ag/AgCl) is used to convert the potential in an aqueous solution to the wire. It acts as a reference electrode, providing a stable and known potential. The electrode consists of a silver wire coated with silver chloride, which acts as the anode.
When the electrode is placed in the aqueous solution, a redox reaction occurs at the electrode surface. The silver metal in the electrode is oxidized to form silver ions (Ag+), and the chloride ions in the solution are reduced to form solid silver chloride (AgCl).
