In the table of standard reduction potentials, locate the half- reactions for the reductions of the following metal ions to the metal. Among the metal ions and metals that make up these half- reactions, answer the following questions. (a) Which metal ion is the weakest oxidizing agent? + Ag (aq) 2+ (Có (aq) (aq) 4+ Zr 2+ 4+ + 2+ Ag¹(aq), Co (aq), Zr* (aq), Cut (aq), 2+ Pt (aq) 2+ Cu (aq) (aq) 2+ Pt (aq) 2+ O Cd (b) Which metal ion is the strongest oxidizing agent? + Ag (aq) 2+ (Có (aq) 4+ Zr (aq) 2+ Cu (aq) (aq) 2+ Pt (aq) 2+ Cd²+ (aq), 2+ Cd (c) Which metal is the strongest reducing agent? Ag(s) Co(s) Zr(s) Cu(s) Cd(s) Pt(s)

(d) Which metal is the weakest reducing agent? Ag(s) Co(s) Zr(s) Cu(s) Cd(s) Pt(s) (e) Will Ag(s) reduce 2+ Co (aq) to Co(s)? Yes No This cannot be determined from the data. (f) Will Zr(s) reduce 2+ Cu (aq) to Cu(s)? Yes No This cannot be determined from the data. (g) Which metal ions on the list can be reduced by Cd(s)? (Select all that apply.) + Ag (aq) 2+ Có (aq) 4+ Zr (aq) 2+ Cu (aq) 2+ Cd²+ (aq) 2+ Pt (aq) None of the above
