1.

Electric current is passed through two cells A and B series. Cell A contains aq. AqNO_(3) and platnium electrodes while cell B contains sq. CuSO_(S) and copper electrodes.

Answer»

The cathode and anode REACTIONS occuring in the two cells are different
The cathode reactions in the two cells are identical but the anode reactions are different
The cathode reactions in the two cells are different but the anode reactions are identical
Electrolysis occurs only in CELL A and in cell B

Solution :In any ELECTROCHEMICAL cell, at cathode reduction reaction and at anode oxidation reaction OCCURES.
