Assuming a temperature of 25 °C, perform the first calculation in the Calculations section of this experiment (E° for Cu = 0.340 V)
Based on the reduction potentials provided below, determine E° for a galvanic cell constructed from these half-cells. Be sure to show all of your work.
Ag+(aq) + 2S2O32-(aq) Ag(S2O3)23- (aq)
1. Ag+(aq) + e- → Ag(s) E° = 0.799 V (at 25 °C)
2. Ag(S2O3)23- (aq) + e- → Ag(s) + 2S2O32-(aq) E° = 0.017 V (at 25 °C)
