Which one of the following figures correctly describes the process
of electrolytic refining?
Answer
Electrolytic refining is a process of refining of metals by electrolysis .
- Cathode is the negative electrode and anode is a positive electrode .
- The current flows from anode to cathode
- The impure Cu electrode is placed at the anode, and pure Cu is placed at the cathode.
- Cu ions being positively charged accumulate on the cathode .
Only figure C represents it correctly.
So, the correct
answer is
(c)
