6L #7c

I am very confused how the book got a cell diagram that contained KOH as the aqueous compound on the anode side instead of just OH-. Also why is there Ni(s) on the cathode side and no OH- present?

i'd guess KOH is used because it is a completely soluble salt of OH- that does not interact with the desired reaction in any way. it probably could have also been NaOH? i don't really understand why we can't just write OH- like we did in 6L.7b but maybe someone else can chime in on that...
