Ein elektrochemisches Element, das aus zwei Halbzellen besteht, in denen Oxidation und Reduktion ablaufen.

Verlust von Elektronen durch ein Atom oder Ion (z.B. Zn zu Zn²⁺).

Gewinn von Elektronen durch ein Atom oder Ion (z.B. Cu²⁺ zu Cu).

Verbindung zwischen den Halbzellen, die den Ladungsausgleich ermöglicht, während sie den direkten Kontakt der Lösungen verhindert.

A copper-zinc element (Daniell element) is demonstrated in the simulation
Zinc is placed in zinc sulfate solution, and copper in copper sulfate solution
Zinc is less noble than copper, and its reduction potential is higher.
Zinc atoms oxidize to Zn²⁺ ions in solution, releasing electrons within the zinc electrode.
This results in a negative charge buildup on the zinc electrode.
Copper ions (Cu²⁺) in solution are reduced to copper atoms at the copper electrode, gaining electrons from the circuit.
A current flows between the two electrodes connected by a wire.
A salt bridge (filter paper soaked in KCl) is used to maintain charge neutrality in the solutions.
SO₄²⁻ anions move toward the zinc electrode.
Zn²⁺ cations move toward the copper electrode.
