Question

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

Options

• Electrons flows from copper electrode to zinc electrode 

• Currents flows from zinc electrode to copper electrode 

• Cations moves towards copper electrode 

• Cations·moves towards zinc electrode

Answer 1

Cations moves towards copper electrode

Explanation:

In Daniel cell, following reaction occurs.

\[\ce{Zn + Cu{2+} -> Zn^{2+} + Cu}\]

At cathode;	\[\ce{Cu^{2+} + 2e^- -> Cu}\]
At anode;	\[\ce{Zn -> Zn^{2+} + 2e^-}\]

Electricity travels from the cathode (Cu) to the anode (Zn) as electrons migrate from one to the other. Cations travel in this area toward the copper cathode electrode.
