On the basis of the electrochemical series, which of these ions will show the greater tendency to be discharged at the cathode in an electrolytic cell
-
cu\(^{2+}\)
- sn\(^{2+}\)
- fe\(^{2+}\)
- zn\(^{2+}\)
The correct answer is: A
Explanation
The arrangement of elements in order of increasing electrode potential values is called electrochemical series.
K > Na > Ca > Mg > Al > Zn > Fe > Ni > Sn > Pb > H > Cu > Ag > Au.
