The method that is used for the making of copper sulphate crystals would be discussed below in details.
What are crystals?
Crystals are solid structures of a compound which are arranged in a definite pattern.
The method of production of pure crystals of copper sulphate is discussed below:
- place some sulfuric acid in a conical flask and warm it in a water bath
- add a spatula of copper oxide powder to the acid and stir with a glass rod
- continue adding copper oxide powder until it is in excess
- filter the mixture to remove the excess copper oxide
- pour the filtrate (the copper sulfate solution) into an evaporating basin
- heat the copper sulfate solution to evaporate half of the water
- pour the solution into a watch glass and leave to allow all of the water to evaporate.
