Determine the overall cell reaction and E
cell
(at 25°C) of a Zn electrode in a 1.0 M Zn(NO3)2 solution
and a Co electrode in a 1.0 M Co(NO3), solution. E (Zn²*/Zn) = -0.76 V, E° (Co²+/Co) = -0.28 V.
What reaction occurs in the cell?
Zn(s) + 2H*(aq) → Zn²“(aq) + H2(g)
Co*(aq) + Zn(s) → Co(s) + Zn²*(aq)
