Answer:
A
Explanation:
Electrolysis has to do with the decomposition of a solution by the passage of direct current through it. Current enters and leaves the electrolyte via electrodes.
The positive electrode is called the anode while the negative electrode is called the cathode. Positive ions move towards the cathode while negative ions move towards the anode.
Cu^2+ moves towards the cathode and accepts two electrons to be deposited on the cathode as metallic copper. Also, Cl^- ions move towards the anode and gives up electrons to become oxidized to chlorine gas.
Hence in the electrolysis of CuCl2, copper is obtained at the cathode while chlorine gas is obtained at the anode. Hence 1 and 3 are correct statements.
