Answer»

Solution :`(Ato4),(Bto3),(Cto1),(Dto2)`.
(A) Lead storage cell : OXIDATION REACTION of Ph occur on Anode.
`Pb_((S))+SO_(4(aq))^(2-) to PbSO_(4(S))+2e^(-)`
Reduction reaction of `PbO_(2)` occur on CATHODE.
`PbO_(2(S))+SO_(4(aq))^(2-)+4H_((aq))^(+)+2e^(-) to PbSO_(4(S))+2H_(2)O_((l))`
(B) Mercury cell does not possess any ions so it have constant potential.
(C) Fuel cell possess high combustible capacity, in which lose of energy is minimum and rest has more combustible energy.
(D) To stop corrosion of metals, the thin layer of metal is PLATED over the metal, means electroplating is carried out. for example, active Zn metal layer is plated in galvanized metal plate of iron.
