describe the process of electrolytic refining …

Electrolytic refining is a process of purification of metals which are highly reactive in nature . For example: sodium , magnesium, aluminum etc. So basically in this process, 1.The impue metal is made the anode and the pure metal is made the cathode. 2. A solution of metal salt is used as electrolyte (in aqueous form) in which small amount of acid is mixed 3. On passing the current the pure metal from the anode dissolves in the electrolyte and gets deposited on cathode (because metals are electopositive as they form +ve ions so the attracts the -ve electrode and depositd on it) 4.The impurities go into the solution and settle down at the bottom of anode and are called anode mud. I hope you understood all this process Thanks
