Question

electrolytic refining process​

Answer 1

In such a process,

Our aim is to obtain pure highly reactive metals from their naturally existing form.

In this process, the impure metal is taken as the anode and a strip of pure metal is taken as the cathode, a salt solution of the respective metal is taken as the electrolyte.

Once electricity is passed through the solution. A certain amount of metal from the anode gets shifted towards the electrolyte and an equal amount of this metal gets deposited from the electrolytic solution to the cathode. The soluble materials gets dissolved in the solution whereas the insoluble materials gets settled at the bottom of the anode and is called as anode mud.

Hope it helps, if it does, please mark as brainliest :))
