Topic Summary: Electrolysis of Molten Compounds
Key Terms
- Cathode — negative electrode (reduction)
- Anode — positive electrode (oxidation)
- Cation — positive ion, moves to cathode
- Anion — negative ion, moves to anode
- Molten — melted; ions free to move
- Half equation — shows electron transfer at one electrode
Must-Know Facts
- Solid ionic compounds do NOT conduct electricity
- Molten compounds conduct — ions are free
- Cathode (−): cations gain electrons → METAL
- Anode (+): anions lose electrons → NON-METAL
- PbBr₂: Pb at cathode, Br₂ at anode
- NaCl: Na at cathode, Cl₂ at anode
- Ions carry current inside electrolyte (not electrons)
