Question

2. The relationship between a cathode and an anode involves

Answer 1

Answer is: electrons.

For example, balanced equation for the overall reaction:

C₂H₅OH + 3O₂ → 3H₂O + 2CO₂.

Galvanic cell has anode and cathode and half reactions are:

Anode reaction: C₂H₅OH + 3H₂O → 12H⁺ + 12e⁻ + 2CO₂; oxidation.

Cathode reaction: 3O₂ + 12H⁺ + 12e⁻ → 6H₂O; reduction.

Electrons are transported from anode to cathode.

Answer 2

I think the answer is electrons. The relationship between a cathode and an anode involves electrons. Hope this helped! :)
