Question
- The following standard reduction potentials have been determined for the chemistry of indium:
In3+(aq) + 2e– ------ In+(aq) E° = –0.40 V
In+(aq) + e– -------- In(s) E° = –0.21 V
Calculate the cell potential, E°, and Keq for the disproportion of In+ at 25°C: 3 In+(aq) ------ 2 In(s) + In3+(aq)
E° = +0.19 V
