Topic Summary: Making Salts
Key Terms
- Crystallisation: forming crystals by cooling concentrated solution
- Filtration: removing insoluble solid from liquid
- Evaporation: removing water to concentrate solution
- Precipitation: forming insoluble solid by mixing two solutions
- Excess: more than needed to react completely
Must-Know Facts
- Soluble salt: react acid + insoluble base with excess base; filter, evaporate, cool, dry
- Insoluble salt: mix two solutions; filter precipitate; wash with distilled water; dry
- All nitrates are soluble; all Na/K/NH₄ salts are soluble
- Insoluble: AgCl (white), BaSO₄ (white), PbI₂ (yellow)
- Add EXCESS BASE not excess acid
- FECD: Filter, Evaporate, Cool, Dry
