Why do we have to use 2H2O-->O2 + 4H + 4e- in this problem. Also where do they get the value of 1.23 for Enaught and why is Ni2+ half reaction the cathode and not the anode even though we have typically tried to create the most positive E.

I was also really having trouble with this and found this old post: viewtopic.php?t=3354 the explanations in the answers are pretty helpful in understanding the Enaught value!
