Problem
Describe how you would prepare some crystals of hydrated copper(II) sulfate from copper(II) oxide and dilute sulfuric acid. Draw a diagram of the apparatus you would use and write a balanced chemical equation for the reaction.Intuitive explanation
This is about acid–base neutralization and crystallization—turning a solid oxide into a soluble salt, then recovering it as crystals. The key insight is that copper(II) oxide is a base that reacts with the acid to form a dissolved salt; you then evaporate the water to let crystals grow. You'll need to think about how to mix them safely, filter out any unreacted solid, and control evaporation to get nice crystals rather than a crusty mess.
