Draw a neat labelled diagram of electrolytic cell used in the extraction of Aluminium by Hall - Heroult Process. Write the reactions take place at cathode and anode.

Answer»

SOLUTION :At ANODE, `C_((s))+O^(2-)rarrCO_((G))+2e^(-)`
`C_((s))+2O^(2-)rarrCO_(2(g))+4e^(-)`
At CATHODE, `Al^(3+)+3e^(-)rarrAl_((l))`
