Given below are half cell reactions:
Will the permanganate ion, 
liberate 
from water in the presence of an acid?
A
No because 
B
Yes, because 
C
No, because 
D
Yes, because 
Text Solution
Verified by ExpertsThe correct answer is:
B
The first half cell reaction is given as,
Here oxidation state of Mn in reactant is +7 and in product, is +2 . It means reduction is occurring here. Therefore, it will take place at cathode.
Second half cell reaction is given as:
Therefore, it will take place at anode. From both the half cell reactions, the complete balanced reaction will be:
Positive 
value suggests that the given hall cell reactions will occur.
