Making a pure salt

  1. 3 stages of making a pure salt areā€¦
    • 1. Reacting an insoluble base with hot acid
    • 2. Filter unreacted oxide
    • 3. Evaporation of salt solution
  2. step 1 of 3; Making a pure salt

    Eg copper sulfate crystals
    • Insoluble base- copper oxide
    • Hot acid- sulfuric acid

    • Heat mixture
    • Add copper oxide to acid until no more will react
  3. Step 2 of 3; Making a pure salt

    Eg copper sulfate
    • Let the solution cool
    • Filter the solution through a filter funnel with paper
  4. Step 3 of 3; Making a pure salt

    Eg copper sulfate
    • Heat the mixture to speed evaporation (this will turn the water particles gaseous)
    • The copper sulfate ions will combine to make pure copper sulfate crystals
