Question

What role does the wire play in voltaic cell?

Answer 1

Answer;

a) It allows electrons to flow from the anode to the cathode.

Explanation;

• Voltaic cell is an electrochemical cell in which a spontaneous chemical reaction produces the flow of electrons.
• Electrons are produced by the oxidation reaction occurring at the anode. Electrons flow through the conducting wire from the anode to the cathode. At the cathode these electrons are used to reduce copper(II) ions to copper atoms.
• A conducting wire or a wire play connects the two electrodes allowing electrons to flow from the anode to the cathode.
