Making salts (1)

• (1) Making salts aim:

  Aim to produce a dry and soluble salt from an insoluble oxide/carbonate
• (1) Making salts - method 1-4:

  
  

  1. Measure 20cm3 of dilute sulfuric acid and pour into a beaker
  2. Heat acid gently using a Bunsen burner
  3. Add copper oxide (metal oxide) until it’s in excess
  4. Filter using filter paper and funnel the solution to remove the excess copper oxide
• (1) Making salts - method 5-8:

  
  

  5. Pour solution into evaporating basin

  6. Place on a water bath / over a Bunsen burner until crystals start to form / it reaches it’s crystallisation point

  7. Leave the evaporating basin in a cool place to crystallise

  8. Gently pat the crystals dry between two pieces of filter paper
