Making Salts

• Soluble salts can be created by reacting an acid with an insoluble base:

  • Add base to acid to produce soluble salt and water
  • Excess solid will sink to the bottom of the flask
  • Filter solution to remove excess solid and leave only salt and water
  • Heat solution to evaporate some water and allow to try
  • Allow it to crystallize and filter solid and leave to dry
• To make a pure sample of insoluble salt, a precipitation reaction can be used:

  • Pick two soluble salts and react them
