Textbook Problem

In the table of standard reduction potentials, locate the half-reactions for the reductions of the following metal ions to the metal: Sn2+(aq), Au+(aq), Zn2+(aq), Co2+(aq), Ag+(aq), Cu2+(aq). Among the metal ions and metals that make up these half-reactions:

  1. (a) Which metal ion is the weakest oxidizing agent?
  2. (b) Which metal ion is the strongest oxidizing agent?
  3. (c) Which metal is the strongest reducing agent?
  4. (d) Which metal is the weakest reducing agent?
  5. (e) Will Sn(s) reduce Cu2+(aq) to Cu(s)?
  6. (f) Will Ag(s) reduce Co2+(aq) to Co(s)?
  7. (g) Which metal ions on the list can be reduced by Sn(s)?
  8. (h) What metals can be oxidized by Ag+(aq)?

(a)

Interpretation Introduction

Interpretation:

The metal ion which is the weakest oxidizing agent has to be determined.

Concept introduction:

Under certain conditions a cell potential is measured it is called as standard potential (Ecello).

Standard potential (Ecello) can be calculated by the following formula.

Ecello=Ecathodeo-Eanodeo

The Ecello value is positive, the reaction is predicted to be product favoured at equilibrium.

The Ecello value is negative, the reaction is predicted to be reactant favoured at equilibrium.

Electrochemical series:

It is an decreasing order of the reduction potentials. The most positive E0 are placed in the top in the electrochemical series , it has greater tendency for reduction and lower tendency of oxidation. And the most negative E0 values of elements are placed in the bottom of the series.

Explanation

Let’s write the electrode potential of each of the following metal ions.

(a) Cu2+(aq) + 2e- Cu(s) ;Eo= +0.337 V(b) Zn2+(aq) + 2e- Zn(s) ;E0= -0.763 V(c) Ag+(aq) + e- Ag(s)   ;E0= +0
