Question

Transcribed Image Text:The following standard reduction potentials have been
measured in aqueous solution at 25°C:
TI+ + e → TI²+
E° = -0.37 V
TI3+ + 2 e → TI*
E° = 1.25 V
(a) Calculate the half-cell potential for the half-reaction
TI2+ +e → TI+
(b) Consider the disproportionation reaction
2 TI²* (aq) = TI³* (aq) + TI* (aq)
Will T²+ disproportionate in aqueous solution?
