Question

A lead storage battery containing 5.0L of H2SO4 solution is operated for 9.65×105s with a steady current of 100 mA. Assuming volume of the solution remains constant, normality of H2SO4 will :



A

increase by unity

loader
B

increase by 0.20

loader
C

decrease by 0.40

loader
D

remain unchanged

loader

Solution

The correct option is A

decrease by 0.40


Anode :
Pb(s)+H2SO4(aq)PbSO4(S)+2H+(aq)+2e
Cathode :
PbO2(s)+H2SO4(aq)+2H++2ePbSO4(s)+2H2O2 mol of H2SO4 consumed. of H2SO4=2×96500C.
Hence, equiv. of H2SO4 consumed
=4×100×103×9.65×1052×96500=2;
decrease in normality =25
