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

Options

  1. AElectrons flow from copper electrode to zinc electrode.
  2. BCurrent flows from zinc electrode to copper electrode.
  3. CCations move toward copper electrode.
  4. DCations move toward zinc electrode.

Correct answer

C. Cations move toward copper electrode.

Step-by-step solution

In Daniell cell, during the passage of electric current through external circuit, electrons flow from the zinc electrode to the copper electrode. At the zinc electrode, the zinc metal is oxidised to Zn++\mathrm{Zn}^{++}which go into the solution. The electrons released at the electrode travel through the external circuit to the copper electrode where they are used in the reduction of Cu2+\mathrm{Cu}^{2+} ions to metallic copper which is deposited on the electrode.
