Making a soluble salt from an insoluble base template
Premium template. Preview and edit it free in MolDraw; downloading and exporting it is part of MolDraw Pro.
GCSE / high school required practical: excess CuO stirred into warm dilute H₂SO₄ in a beaker on a tripod and gauze, then filtered into a conical flask; the blue filtrate is evaporated and crystallised.
What the template shows
- Copper(II) sulfate crystals from copper(II) oxide and dilute sulfuric acid
- Stir in CuO
- Add it a spatula at a time until some stays undissolved, so all the acid is used up
- Warm dilute H₂SO₄
- CuO + H₂SO₄ → CuSO₄ + H₂O; warm gently, do not boil
- Bunsen burner
- Small blue flame under a tripod and gauze
- Filter funnel
- Filter paper holds back the excess black CuO
- Blue filtrate
- CuSO₄ solution: evaporate to about half over a water bath, then leave to crystallise; dry the crystals on filter paper
- Reaction setup
Drawn with 14 shapes – every one editable in MolDraw.
