6O.1 b

Postby Gabriella Bates 2L » Sat Mar 07, 2020 4:34 pm

"A 1.0 m NiSO4(aq) solution was electrolyzed by using inert electrodes. Write (a) the cathode reaction; (b) the anode reaction. (c) With no overpotential at the electrodes, what is the minimum potential that must be supplied to the cell for the onset of electrolysis?"

For part b, I understand that the anode reaction will be 2H2O --> O2 +4H+ + 4e-, but in the book they used E = 1.23V instead of 0.82V. Do we use this value becuase we assume the reaction takes place at standard conditions, instead of when pH = 7?

Yes we assume standard conditions
