The anodic half-cell of lead-acid battery is recharged using electricity of 0.05 Faraday. The amount of PbSO4 electrolyzed in g during the process is : (Molar mass of PbSO4 = 303 g mol −- 1)

Multiple Choice Options

  • A 22.8
  • B 15.2
  • C 7.6
  • D 11.4

Step-by-Step Verified Solution

Pb(s) + SO 4−2_4^{ - 2}   →\to   PbSO4 + 2e −-

nPbSO41=ne−2{{{n_{PbS{O_4}}}} \over 1} = {{{n_{e - }}} \over 2}

⇒\Rightarrow     nPbSO41=0.052{{{n_{PbS{O_4}}}} \over 1} = {{0.05} \over 2}

∴\therefore   Weight of PbSO4 == 0.052×303=7.6g{{0.05} \over 2} \times 303 = 7.6g
