Question
During electrolytic refining of copper, it gets(a) Deposited on cathode (b) Deposited on anode(c) Deposited on cathode as well as anode (d) Remains in the solution
Solution
During the electrolytic refining of copper, it gets (a) Deposited on the cathode.
Here's the step-by-step process:
-
An electrolytic cell is set up to refine impure copper. The impure copper is made the anode (positive electrode) and a sheet of pure copper is made the cathode (negative electrode).
-
The electrolyte (the medium that allows the flow of electric charge) used is an acidic solution of copper sulphate (CuSO4).
-
When electricity is passed through the cell, copper from the impure anode is dissolved into the electrolyte as copper ions. These copper ions are attracted to the cathode, where they gain electrons and deposit as pure copper.
-
Impurities from the anode either dissolve into the electrolyte or fall to the bottom of the cell as anode sludge.
So, the copper gets deposited on the cathode during the electrolytic refining process.
