Write chemical equations on anode and cathode of lead storage cell​

Answer»

Answer:

Explanation:

plz mark as brainliest answer and thx for the brainliest answer even follow me

hey DUDE....

here is ur answer..!!!!!!

The reactions which take place in the cell during DISCHARGE (when current is drawn from the cell) are,

At anode: (oxidation)

Pb + SO42–→PbSO4(s) + 2e–

At cathode: (reduction)

PbO2(s) + 4H++ SO42–+ 2e– → PbSO4(s) + 2H2O

Net cell reaction:

Pb + PbO(s) + 4H+ + 2SO42– → 2PbSO4(s) + 2H2O.

thanks.....!
