Question

1. The process of electrolysis can be used for the purification of copper. In this process, a thin plate of pure copper and a thick rod of impure copper are used as electrodes. Copper from the impure rod is sought to be transferred to the thin copper plate. Copper sulphate solution is used for this process. Answer the following questions with the information that you have now–
(a) Explain, how does copper from impure copper gets deposited over the thin plate of copper?
(b) Write the chemical reactions that occur on-Anode, Cathode, and in the Solution in this process.

Answer 1

Answer:

A thick rod of impure copper should be attached to the positive terminal of the battery.

The thin plate of copper should be attached to the negative terminal of the battery.

This is because the copper ions from the positive terminal will get attracted to the negative terminal.

The copper ions from the impure copper will get accumulated on the pure copper plate.
