Experiment Electrode Zinc Sheet Fruit Battery
The Zinc Electrode Sheet is a key component in hands-on educational experiments such as fruit batteries and simple voltaic cells. Commonly used in school science projects and electrochemical demonstrations, this zinc sheet serves as the anode in galvanic cells, where it undergoes oxidation to release electrons and generate electric current. Its compact size and conductive properties make it ideal for exploring the principles of redox reactions and the chemistry behind battery technology.

Chemistry Behind Zinc-Based Galvanic Cells
A battery is a device made of one or more galvanic cells used to store and produce electric energy via chemical reactions. Each galvanic cell has two half-cells: one for reduction and one for oxidation. Zinc is commonly used as the anode (oxidation electrode) in these cells.
In a typical fruit battery, the zinc electrode undergoes oxidation: Zn → Zn²⁺ + 2e⁻
Oxidation-Reduction Reactions (Redox)
In electrochemistry, oxidation means the loss of electrons, while reduction is the gain of electrons. This can be remembered as LEO (Lose Electrons = Oxidation) and GER (Gain Electrons = Reduction).
Zinc acts as the reducing agent in the reaction, donating electrons to complete the circuit when paired with a suitable oxidizing agent such as copper.
Example: Copper-Zinc Voltaic Cell
In a simple voltaic cell, zinc serves as the anode and copper as the cathode. The spontaneous redox reaction between them generates electricity.
Zinc Reaction: Zn (s) → Zn²⁺ (aq) + 2e⁻
Copper Reaction: Cu²⁺ (aq) + 2e⁻ → Cu (s)
The flow of electrons from zinc to copper provides usable electric current in educational battery experiments.
