Chemistry Question on Electrochemistry
Consider the following electrodes
P = Zn2+ (0.0001 M)/Zn Q = Zn2+ (0.1 M)/Zn
R = Zn2+ (0.01 M)/Zn S = Zn2+ (0.001 M)/Zn
E°Zn/Zn2+ = 0.76 V Electrode potentials of the above electrodes in volts are in the order
A
P > S > R > Q
B
S > R > Q > P
C
Q > R > S > P
D
P > Q > R > S
Answer
Q > R > S > P
Explanation
Solution
The correct answer is (C) : Q > R > S > P.
