GCSE Chemistry - Purity and Formulations #62

The video tutorial covers chemical analysis, focusing on purity and formulations. It explains the concept of pure substances, their specific melting and boiling points, and how these properties help identify unknown substances. Impure substances, like mixtures, have a range of melting and boiling points. The tutorial also introduces formulations, which are precise mixtures designed for specific functions, such as paints or medicines.
