Question

Which reaction occurs at the cathode of a lead-storage battery that is being recharged?

A. 2e− + PbO2 + 4H+ + SO42− ----> PbSO4 + 2H2O
B. PbSO4 + 2H2O ----> 2e− + PbO2 + 4H+ + SO42−
C. Pb + SO42− ----> PbSO4 + 2e−
D. PbSO4+ 2e− ----> Pb + SO42−

Answer 1

@DanJS

Answer 2

The anode reaction of the discharge , in reverse. Let me find that again...

Answer 3

Pb + HSO4− → PbSO4 + H + + 2e −

the reverse of that

Answer 4

Without the H+ in there

Answer 5

D. PbSO4+ 2e− ----> Pb + SO42−

Answer 6

hows that ?

Answer 7

thank you

Answer 8

was that right

Answer 9

yes lol

Answer 10

yay, i am learning with you
