How do you prepare a soluble salt with an acid and insoluble chemical?
Crystallisation, acid is added to:
- metal
- insoluble base
- carbonate
Alkali metals (too reactive) or compounds with alkali metals (soluble) cannot use this method.
How do you prepare a soluble salt with an acid and soluble chemical?
Titration (Crystallisation with extra steps)
What are the differences between preparing salts via titration and crystallisation?
Crystallisation:
- Uses one soluble substance
- No indicator needed
- Impure substance collected
Titration:
- Uses soluble acid and base
- Indicator needed
- Pure substance collected
How do you prepare an insoluble salt?
Precipitation, where:
Soluble salt + soluble salt -> insoluble salt + soluble salt
