Concept introduction: Voltaic cell or Galvanic cell: The device to produce electricity by using chemical reactions . In these divces are redox chemical reactions are occured. A voltaic cell converts chemical energy into electrical energy. It consists of two half cells. Each half cell consists of a metal and a solution of a salt of metal. Two half cells are connected by salt bridge. The chemical reaction in the half cell is an oxidation reduction (redox)reactions. For example: Cell diagram of voltaic or galvanic cell is as follows.
