In an electrochemical series Ni|Ni²+(0.01M) || cu²+(0.1M) |cu cell potential is found to be 0.59v calculate the standard electrode potential of Ni electrode given that Enot of cu²+ | cu is 0.34v ​

​

Answer 1

E° cell=E°Right or cathode - E°Left or anode

0.59=0.34 - E°Ni^+2 0.34

0.59 -0.34 = -E°Ni^+2

E°Ni^+2=-0.25
