Question

(a) Illustrate the arrangement of refining copper and label the anode, cathode and electrolyte.
(b) Write the chemical equation at the anode and cathode and sustain it as redox reaction.

Answer 1

a. Refer Image

b. Anode - $Cu\to C{u}^{2+}+2e$
Cathode - $C{u}^{2+}+2e\to Cu$
As oxidation and reduction takes place it is a redox reaction.
