QAIPM-2011-Ch-1870: NEET 2011 Chemistry - Class 12 AIPM-2011-Ch-1870 Solution: The electrode potentials for \(Cu^{2+}(aq)+e^- Cu^+(aq)\) and…

The electrode potentials for

Cu^{2+}(aq)+e^-\rightarrow Cu^+(aq)

and

Cu^+(aq)+e^-\rightarrow Cu(s)

are +0.15 V and +0.50 V respectively. The value of

E^\circ_{Cu^{2+}/Cu}

will be

Multiple Choice Options

A 0.500 V
B 0.325 V
C 0.650 V
D 0.150 V

Step-by-Step Verified Solution

Cu 2+ (aq) + e _ _ Cu + (aq) ; E 1 o = 0.15 V Cu + (aq) + e _ _ Cu (s) ; E 2 o = 0.50 V Cu 2+ + 2e � _ Cu ; E o = ? _ G o = _ G 1 � + _ G 2 � _ � nFE� = � n 1 FE 1 � � n 2 FE 2 � _ E o = 1 _ 0.15 + 1 _ 0.50 2 = 0.325 V
