The anodic half-cell of lead-acid battery is recharged using electricity of 0.05 Faraday. The amount ofPbSO4electrolyzed (in g) during the process is (Molar mass ofPbSO4=303 gmol-1)

Options:

Answer:
C
Solution:

A PbSO 4 s 0.05/2 +2 OH − → PbO 2 + H 2 SO 4 + 2 e − 0.05F
C PbSO 4 s 0.05/2 + 2 e − 0.05F +2 H + →Pb s + H 2 SO 4
n PbSO 4 = 0.05 2  mole
w PbSO 4 = 0.05 2 ×303=7.6 gm
