Question
Consider the following half-reactions.
  Cl2(g) + 2 e → 2 Cl(aq) E° = +1.36 V
  Ag+(aq) + e → Ag(s) E° = +0.80 V
  Cu2+(aq) + 2 e → Cu(s) E° = +0.34 V
  Sn2+(aq) + 2 e → Sn(s) E° = –0.14 V
  Al3+(aq) + 3 e → Al(s) E° = –1.66 V

Which of the following species will reduce Cu2+(aq) ion?

Ag(s) and Sn^2+(aq)

Cl^-(aq) and Ag(s)

Cl2(g) and Ag^+(aq)

Sn(s) and Al(s)

Sn^2+(aq) and Al^3+(aq)
