When the silver electrode having reduction potential 0.80 V is attached to NHE , will it act as anode or cathode ?

Text Solution

Verified by Experts

As reduction potential of silver electrode is +ve while that of NHE is '0', EMF of the cell will be +ve only if reduction takes place at the silver electrode i.e., it will act as cathode.
