A
volts
B
; 
volts
C
volts
D
volts
Text Solution
Verified by ExpertsThe correct answer is:
A
: During electrolysis of aqueous 
following oxidation reactions are possible:
The reaction at anode with lower value of 
is preferred and therefore, water should get oxidised in preference to 
. However, on account of overpotential of oxygen, reaction (i) is preferred.
Thus,
Cathode: 
Anode :
