Consider the following reactions:
Zn^2+ + 4H3 <----> Zn(NH3)4^2+ beta 4 = 5.01 x 10^8
Zn^2+ + 2e^- <-----> Zn(s) E degree = -0.762 V
Assuming there is negligible current and nearly all Zn^2+ is inthe form Zn(NH3)4^2+. what cathode potential (vs. S.H.E.) would berequired to reduce 99.99% of the Zn^2+ from a solution containing0.20 M Zn^2+ in 1.4 M ammonia? (Assume T= 298 K)
