    If you react copper oxide and hot dilute sulfuric acid, and allow all the water to evaporate, a white solid forms.

    Is this because there is no water for water of crystallisation?

    Also, is the reason the acid is hpt just to increase the reaction rate?

    The product is CuSO4 (copper sulphate). Which is a blue solution/blue crystals or a white powder in anhydrous form.
    Crystallization doesn't occur just because some of the water has been evaporated. Crystallization involves heating and cooling, where the latter is very important.

    Since the sulfate is formed, sulfuric acid is a reactant, not a catalyst.

    Hope this helps.
