Consider the following four electrode :
`A = Cu^(2+) (0.0001 M)// Cu(S)` B=`Cu^(2+) (0.1M)//Cu(s)`
C =`Cu^(2+) (0.01 M )//Cu(s)` D) `= Cu^(2+) (0.001 M )// Cu(s)`
If the standard reduction potential of `Cu^(+2)// Cu` is + 0.34 V , the reduction potential ( in volts ) of the above electrodes follow the order
