The electrode potentials for Cu2+ + e- -------- Cu+(aq) and Cu+(aq) + e- ------- Cu(s) are +0.15V and +0.50V respectively. The value of ECu2+/Cu will be?
1- 0.15V 2- 0.5V
3-0.325V 4- 0.650V
Cu2+ + e ............... Cu+ E= +0.15 V
Cu+ + e ............... Cu E= +0.50 V
Ecell = Ecathode - Eanode
ECu2+/Cu = 0.50 - 0.15 = 0.35V
Cu+ + e ............... Cu E= +0.50 V
Ecell = Ecathode - Eanode
ECu2+/Cu = 0.50 - 0.15 = 0.35V
