Question

What is anode mud?

Answer 1

Hint: When the dissolution of anode is done in commercial electrolysis a deposit of anode residue is collected which is known as anode mud.

Complete step-by-step answer:
Anode mud is a type of deposit which is insoluble in nature. A deposit of anode mud is found in commercial electrolysis as a residue in anode. It is produced while purifying a metal. Another name for anode mud is anode slime. Every year around 80000 tons of anode is produced for purifying silver and gold metals. While purifying the metals the impure metal is taken on anode whereas pure metal is taken over cathode.
When the electrolysis is started all the pure metal ions on the anode start moving towards the cathode where they stick to the outer layer of pure metal whereas impurities dissolve and get collected on the bottom of the beaker which is known as anode mud. Now cathode has pure metal and the bottom of the beaker has impurities. Sometimes this anode mud contains precious metal. Therefore, anode mud are the impurities collected at anode in electrolysis during purification of metals like copper, silver and gold etc.

Note: Anode mud is a type of residue collected when metal is purified by the process of electrolysis. During that process impurities or metal which is not desired dissolve and get deposited on the bottom of the beaker whereas a desired product that is pure metal ions move towards cathode depositing on the outer surface. These impurities at bottom are known as anode mud.
