GCSE / high school to A-level / AP / IB: hydrated copper(II) sulfate heated in a crucible on a pipe-clay triangle, cooled in a desiccator and weighed until the mass is constant.

## What the template shows

- Heat a hydrated salt to constant mass and find x in CuSO₄·xH₂O
- Crucible lid
- Keeps the solid from spitting out; lift it a little to let the water vapour escape
- Crucible + hydrated salt
- About 2 g of blue CuSO₄·5H₂O; it turns white as the water is driven off
- Pipe-clay triangle
- Bunsen burner
- Heat gently, then more strongly; overheating turns the salt black (CuO)
- Crucible tongs
- Cool the crucible here, so the anhydrous salt cannot take water back from the air
- Weigh empty, with the salt, then after each heating; repeat heat, cool, weigh until two masses agree. x = n(H₂O) ÷ n(CuSO₄)
- Reaction setup

## Frequently asked questions

### Is the Water of crystallisation template free?

You can preview the Water of crystallisation template here and open and edit it in MolDraw for free. Downloading or exporting it is part of MolDraw Pro, together with the other premium templates.

### Can I edit the Water of crystallisation template?

Yes. It opens as an ordinary MolDraw drawing, so every structure, arrow, label and colour can be changed, and you can add your own content around it.

### Is the chemistry checked?

Every structure is checked with RDKit and every curly arrow passes MolDraw’s electron-flow audit. The sources used are listed on this page.

### Can I edit the glassware?

Yes. Every piece of glassware is a MolDraw apparatus object: move, resize, recolour the liquid or swap a piece and the joints stay connected.
