प्रश्न
Consider the figure and answer the following question.
Cell ‘A’ has ECell = 2V and Cell ‘B’ has ECell = 1.1V which of the two cells ‘A’ or ‘B’ will act as an electrolytic cell. Which electrode reactions will occur in this cell?
उत्तर
Cell ‘B’ will act as electrolytic cell as it has lower emf
∴ The electrode reactions will be:
\[\ce{Zn^{2+} + 2e^{-} -> Zn}\] at cathode
\[\ce{Cu -> Cu^{2+} + 2e^{-}}\] at anode
