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)
