Testing Water: Presence and Purity

The video tutorial explains how to test for the presence and purity of water. It highlights the importance of water as a solvent and reactant, while also noting its potential to cause corrosion. The presence of water can be tested using hydrated copper sulfate, which changes color when water is present. To test water purity, the boiling point is measured; pure water boils at 100 degrees Celsius. These methods provide simple ways to assess water's presence and purity.
