The figure depicts the electrolysis of mixture of alumina and cryolite. Label anode, cathode and electrolyte in the figure.

Illustrate the arrangement of refining copper and label the anode,cathode and electrolyte.

Purification of copper is depicted here: Identify the anode, cathode and electrolyte.

Alumina is mixed with cryolite and subjected to electrolysis to extract aluminium. Write the equation of the reduction reaction taking place at negative electrode.

What is the importance of adding cryolite in the electrolysis of alumina?

Alumina is mixed with cryolite and subjected to electrolysis to extract aluminium. Why cryolite is added to alumina?

Which substances are used as the anode, cathode and electrolyte when copper is refined by electrolysis.

Give reason a) Cryolite is added during the electrolysis of alumina. b) Carbon rod is replaced from time to time while producing aluminium,

In electrolytic refining of metals, the impure metal is made, the anode and a strip of pure metal,the cathode during the,electrolysis of an aqueons solution of a complex metal salt. This method cannot be used for refining of : silver, copper, aluminium, zinc
