6N.15 anode or cathode

Postby Edmund Zhi 2B » Mon Mar 02, 2020 4:46 pm

We are given 1.0M Ni2+ in one solution, and I have calculated that 6.5 x 10*-12 M of Ni2+ is in the other compartment. How do I determine which is the anode and which is the cathode?

Since it's a concentration cell (because the two electrodes are the same metal), I think you would make whichever is a lower conc as the product in reaction and then balance with electrons to figure out whether it's being oxidized or reduced. How did you calculate the 6.5 x 10^-12M?
