Question 1

Given the following standard reduction potentials,
Ag+(aq) + e–→ Ag(s)
E° = 0.80 V
AgCN(s) + e–→ Ag(s) + CN–(aq)
E° = –0.01 V

calculate the solubility product of AgCN at 25°C.

◦ 4.3 × 10–14

◦ 2.3 × 1013

◦ 2.1 × 10–14

◦ 5.1 × 1013

◦ None of these

Question 2

Given the following standard reduction potentials,
Ag+(aq) + e–→ Ag(s)
E° = 0.80 V
Ag(NH3)2+(aq) + e–→ Ag(s) + 2NH3(aq)
E° = 0.04 V

calculate the formation constant of Ag(NH3)2+at 25°C.

◦ 6.1 × 10–15

◦ 1.5 × 10–13

◦ 6.9 × 1012

◦ 1.6 × 1014

◦ None of these
