Question

Which of the following statements is true for the electrochemical Daniel cell?

• A. Electrons flow from copper electrode to zinc electrode
• B. Current flows from zinc electrode to copper electrode
• C. Cations move toward copper electrode
• D. Cations move toward zinc electrode

Answer 1

Answer: (C)

Cations move toward copper electrode

Daniel celI is an electrochemical cell in which $Cu$ acts as cathode and $Zn$ acts as an anode. In Daniel cell,

(i). Electrons flow from $Zn$ (anode) to $Cu$ (cathode).

(ii) Current flows from $Cu$ (cathode) to $Zn$ (anode).

(iii) $C{u}^{2+}$ions (cations) move towards $Cu$ (cathode) and accumulated as $Cu$ metal.

Hence, the correct option is $C$
