Question

Explain why sometimes anode mud is more useful and important than the metal being refined?​

Answer 1

Answer:

Anode mud: Impurities collected at anode in electrolysis during purification of metals.

During electrorefining process pure zinc gets deposited at the cathode and an equivalent amount of metal dissolves from the anode into the electrolyte in the form of metal ions. Also, impurities settle down below the anode in the form of anode mud.

Example: Electrorefining of Cu

At cathode:

Cu

2+

+2e

→

Cu

At anode:

Cu+2e

→

Cu

2+

Answer 2

Answer:

anode attracts negative charge and separate the elements
