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

Options

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

C

Explanation

In Dnaiel cell,during the passage of electric current through external circuit,electrins flow from the zinc electrode to the copper electrode.At the zinc electrode,the zinc metal is oxidised to`Zn^(++)`which go into the solution.The elctrons released at the electrode trsvel through the external circuit tothe copper electrode where they are used in the reduction of`Cu^(2+)`ions to metalic copper which is deposited on the electrode.
