Flowchart showing the components and function of a galvanic cell

Flowchart showing the components and function of a galvanic cell

The map in words

  • Galvanic Cell Components
    • Anode (Oxidation) Negative electrode
      • Loses electrons: Zn → Zn²⁺ + 2e⁻
    • Cathode (Reduction) Positive electrode
      • Gains electrons: Cu²⁺ + 2e⁻ → Cu
    • Salt Bridge Maintains electrical neutrality
      • Ion flow: Internal circuit K⁺, Cl⁻ ions
    • External Circuit Electrons flow here
      • Electron flow: Powers devices Galvanometer reads current

The map in words

  • Anode → SB: Zn²⁺ ions accumulate Excess positive charge
  • SB → Anode: Cl⁻ ions migrate in
  • Anode → Anode: Electrical neutrality restored
  • Cathode → SB: Cu²⁺ ions consumed Excess negative charge
  • SB → Cathode: K⁺ ions migrate in
  • Cathode → Cathode: Electrical neutrality restored
  • Cell continues to function
