The reaction taking place in a galvanic cell is given. The identity of the unknown metal used in combination with Aluminum for the construction of given galvanic cell is to be stated. Concept introduction: The galvanic cell converts chemical energy into electrical energy while the electrolytic cell converts electrical energy into chemical energy. The species at anode undergoes oxidation, while the species at cathode undergoes reduction and the electrons generated at the anode are transferred through wire to the cathode. The relationship between cell potential and Gibbs free energy change is given by the formula, Δ G ° = − n F E ° cell To determine: The identity of the unknown metal used in combination with Aluminum for the construction of the given galvanic cell.
