Cd(OH)2(s) +2e- -->Cd(s)+2OH- Enaught=-0.4V
2NiO2(s)+H2O+2e- -->2Ni(OH)2(s)+2OH- Enaught=0.5V
When the nickel-cadmium battery is recharging, what is the reaction at the anode?
Book says the answer is:
2Ni(OH)2(s)+2OH--->2NiO2(s)+H2O+2e-.
Shouldn't the answer be:
Cd(OH)2(s)+2e- -->Cd(s)+2OH-
?
Thank you,
Michael
