Learn how to prepare a sample of pure, dry, hydrated copper sulfate crystals from copper oxide

Mrs Peers Dent from Malmesbury Education uses an excess of copper (II) oxide to neutralise sulfuric acid creating copper sulfate in aqueous solution. She uses filtration and evaporation techniques to produce pure dry crystals of the hydrated salt.

Once students have made a hydrated salt, they may be required to find the formula by calculation. Dr Sarah Sephton talks through different methods to find the formula based on various unknowns.

To be able to calculate the amount of water, you must first dehydrate the sample, as demonstrated in this short video from the Just Add Water lecture series by Dr Peter Wothers.
