A voltaic cell is constructed based on the oxidation of zinc metal and the reduction of silver cations. Solutions of silver nitrate and zinc nitrate also were used. Locate the silver nitrate on the diagram.

The anode (-) half-cell is where oxidation occurs, which is where zinc metal is oxidized to form zinc ions in solution. Thus, the zinc metal electrode is located at position b. Similarly, the cathode (+) half-cell is where reduction occurs, which is where silver cations are reduced to solid silver metal. Thus, the silver half-cell is located at position c, where solid silver is in contact with a solution of silver ions (AgNO3).
