Chemistry Required Practicals

Making Salts:

Activity: Preparation of a pure, dry sample of a soluble salt from an insoluble oxide or carbonate, using a Bunsen burner to heat dilute acid and a water bath or electric heater to evaporate the solution.

Materials needed:

• 40cm3 1.0 mol dilute sulfuric acid
• copper(II) oxide powder
• general lab equipment

Important info:

• 40cm3 of dilute acid will react with approximately 3.2g copper (II) oxide powder, but more than this will be used due to the excess added.
• Do not boil the acid

Safety:

• Safety goggles should be worn throughout.
• 1.0M dilute sulfuric acid (IRRITANT)
• copper(II) oxide (HARMFUL)
• copper(II) sulfate (HARMFUL)
