Question

On charging the lead storage battery, the oxidation state of lead changes from x 1 ​ to y 1 ​ at the anode and from x 2 ​ to y 2 ​ at the cathode. The values of x 1 ​ , y 1 ​ , x 2 ​ , y 2 ​ are respectively :

TestHub · Accepted Answer

For charging of lead storage battery cell reaction is $2 PbSO_{4} (s) + 2 H_{2} O (l) \to Pb (s) + PbO_{2} (s) + 2 H_{2} SO_{4} (aq)$ At anode $PbSO_{4}$ reduced back to Pb and at cathode $PbSO_{4}$ oxidised back to $PbO_{2}$ .
$∵ x_{1} = + 2, y_{1} = 0 x_{2} = + 2, y_{2} = 4$
