17.5 Exercise 2

Avg difficulty 2.5

Consider a battery with the overall reaction: Cu(s)+2Ag+(aq)⟶2Ag(s)+Cu2+(aq).\text{Cu} \left(s\right) + 2 \text{Ag}^{+} \left(a q\right) \rightarrow \text{2Ag} \left(s\right) + \text{Cu}^{2+} \left(a q\right) .

(a) What is the reaction at the anode and cathode?

(b) A battery is “dead” when its cell potential is zero. What is the value of Q when this battery is dead?

(c) If a particular dead battery was found to have [Cu2+] = 0.11 M, what was the concentration of silver ion?
