Answer Text:
Uses / importance of solubility curves:
- Can be used to determine the mass of crystals that would be obtained by cooling a volume of hot saturated solution from one known temperature to
another.
- Solubility differences can be used to separate substances i.e. recrystallization or fractional crystallization (refer to separation of mixtures)
- Separation of salts from a mixture of salts with differing solubilities e.g. extraction of sodium carbonate from Trona (refer to carbon and its compounds)
- Manufacture of certain salts e.g. sodium carbonate by the Solvay process (refer to carbon and its compounds)
