In 1 M NH 3 /1 M NH 4 Cl solution, Cu 2 + is reduced to

Question:

In 1 M NH₃/1 M NH₄Cl solution, Cu²+ is reduced to Cu⁺ near -0.3 (versus S.C.E.), and Cu⁺ is reduced to Cu(in Hg) near - 0.6 V.

(a) Sketch a qualitative sampled current polarogram for a solution of Cu⁺.

(b) Sketch a polarogram for a solution of Cu²⁺.

(c) Suppose that Pt, instead of Hg, were used as the working electrode. Which, if any, reduction potential would you expect to change?
