12,13
please explain answer

12. If an object is to be plated with a metal in an electrolytic cell, the object should be A. made of the metal with which it is to be plated C. used as the anode of the cell B. used as the cathode of the cell D. oxidized by the solution in the cell 13. The salt bridge found in many electrochemical cells is needed to A. transfer ions from one half cell to the other. B. carry electrons between the cathode and anode. C. insulate the two electrodes. D, allow the electrolyte solution of siphon from one side of the cell to the other so the levels remain equal. E. none of the above

Explanation / Answer

12. A:- C. Used as the anode of the cell => in electrochemical cell, at anode the oxidation of metal to metal is takes place, at cathode the reduction of metal to metal atom is takes place.

13. A:- A. Transfer ions from one half cell to the other => which helps for ionic neutrality by migration of ions from one to another side of cell.
