Consider the following 4 electrodes aligned & A : Ag ⁺(0.0001 M ) / Ag (s) & B : Ag ⁺(0.1 M ) / Ag (s) & C : Ag ⁺(0.01 M ) / Ag (s) & D : Ag ⁺(0.001 M ) / Ag (s) ; E^ _ Ag ⁺ / Ag =+0.80 ~V aligned Then reduction potential in volts of the electrodes in the order.
Options
- AB > C > D > A
- BC>D>A>B
- CA>D>C>B
- DA>B>C>D
Correct answer
A. B > C > D > A
Step-by-step solution
According to this equation, as concentration of metal ion increases, reduction potential of metal electrode also increases i.e E concentration. B > C > D > A
