Question

Of the following statements concerning electrochemical cells, the correct ones are:

0 The cell reaction is an oxidation-reduction reaction. 1 If electric current is drawn from a voltaic cell long enough, the cell becomes an electrolytic cell. 2 The cathode is the negative electrode in both voltaic and electrolytic cells. 3 The function of a salt bridge is to permit the migration of electrons between the half-cell compartments of an electrochemical cell. 4 Reduction occurs at the cathode in both voltaic and electrolytic cells. 5 The anode is the negative electrode in a voltaic cell. 6 Electrons leave the cell from either the cathode or the anode, depending on what electrodes are used.

Explanation / Answer
