Label the given diagram showing lead storage battery :

A

`p-Pb, q-PbO_2 , r-5 M H_2SO_4`

B

`p-PbO_2 , q-Pb , r-conc. H_2SO_4`

C

`p-Pb_3O_4 , q-PbO_2 , 50% H_2SO_4`

D

`p-PbO_2 , q-Pb , r-dil. 38% H_2SO_4`

Text Solution

Verified by Experts

The correct Answer is:
D
`PbO_2` plates act as cathode while Pb plates act as anode. Dilute (38%) `H_2SO_4` acts as an electrolyte.
