Consider the following reactions: Zn+4NH, = Zn(NH, Zn2+ + 2e Zn(s) B₁ =5.01 × 108 E° = -0.762 V Assuming there is negligible current and nearly all Zn2+ is in the form Zn(NH3)42*, what cathode potential (vs. S.H.E.) would be required to reduce 99.99% of the Zn2+ from a solution containing 0.18 M Zn2+ in 1.4 M ammonia? (Assume T = 298 K) Number ☐ V
