How do you prepare hydrated copper sulphate?
Method
- place some sulfuric acid in a beaker and warm it in a water bath.
- add a spatula of copper(II) oxide powder to the acid and stir with a glass rod.
- continue adding copper(II) oxide powder until it is in excess.
- filter the mixture to remove the excess copper(II) oxide.

Which method can be used to obtain crystals from aqueous copper II sulphate?
Warm the acid. Add copper(II) oxide until it is in excess. Filter the mixture. Evaporate the filtrate until crystals start to form.
How do you make copper sulfate step by step?
Make Copper Sulfate
- Fill a jar or beaker with 5 ml concentrated sulfuric acid and 30 ml of water.
- Set two copper wires into the solution so that they are not touching each other.
- Connect the wires to a 6-volt battery.
- The solution will turn blue as copper sulfate is produced.

Copper(II) sulfate/Formula
What is the best method of making copper II sulfate?
Method
- Pour 25 cm3 of sulfuric acid into a beaker.
- Add in excess copper(II) oxide.
- Heat the beaker and stir until reaction is complete.
- Filter off the unreacted solid, collecting the clear blue solution in an evaporating dish.
- Boil the solution for 2–3 minutes.
- Let the solution cool and watch the crystals grow.
How will you separate copper sulphate crystals from copper sulphate?
Separating solids from liquids – evaporation Evaporation is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind.
