Question

Which of the following statements is true for electrochemical cell?

विकल्प

• Cations move towards zinc electrode.

• Cations move towards copper electrode.

• Current flows from zinc electrode to copper electrode.

• Electrons flow from copper electrode to zinc electrode.

Answer 1

Cations move towards copper electrode.

Explanation:

In an electrochemical cell like Zn | Zn²⁺ || Cu²⁺ | Cu, the copper electrode acts as a cathode, where reduction of Cu²⁺ to Cu occurs. Since cations are attracted to the cathode, they move toward the copper electrode.
