Transcribed Image Text:3) A voltaic cell is set up at 25 °C with half cells Sn+2 (0.350 M) and Ag+! (0.050 M). Sketch the
voltaic cell. Be sure to label the anode, cathode, and the direction of electron flow.
Information: Snt2 (aq) + 2 e-→ Sn (s)
E° = 0.15 V
Ag +' (aq) + 1 e- → Ag (s)
E° = 0.799 V
2 H' (aq) + 2 e- Hа (9)
E° = 0 V
3b) What is the balanced chemical reaction occurring in this electrochemical cell (spontaneous in
the direction towards products)?
3c) Calculate E° for this reaction.
3d) Calculate Eoell (given the conditions described in the problem)
