Key Stage 4
Meaning
Produce a salt from a Neutralisation reaction between an acid and an insoluble base then separate the salt from the mixture to obtain a pure sample.
Method
- Add roughly 40ml of 1.0M Sulphuric Acid to a 100ml beaker.
- Heat the acid to 90°C.
- Use a spatula to add a small amount of Copper (II) Oxide powder to the solution and stir with a glass rod.
- Repeat step 3 each time the Copper (II) Oxide disappears until the some of the powder remains at the bottom despite stirring.
- Allow to cool then pass the mixture through filter paper and a funnel into a conical flask to remove the Copper (II) Oxide residue, leaving only the solution in the conical flask.
- Pour the solution into an evaporating dish and heat gently to evaporate the water from solution. This will leave pure Copper Sulphate crystals.
