Consider the following potential,
(i) 
(ii) 
(iii) 
(iv) 
(v) 
How many of them will act as cathode when connected to standard hydrogen electrode which has 
value given as zero?
Text Solution
Verified by ExpertsThe correct answer is:
D
Among the given potentials, only two, i.e. (ii) and (iv) will act as cathode when connected to standard hydrogen electrode which has 
value given as zero. As, the value of standard reduction potential is positive, the electrode undergo reduction and acts as cathode.
