Separation of mixtures 9/11/11 introduction: a compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Many compounds contain hydrogen and oxygen, but only one has that special 2 to 1 ratio we call water the compound water has physical and chemical properties different from both hydrogen and oxygen — water's properties are a unique combination of the two elements. Mixtures can be separated into these components by using physical methods like, decantation, distillation, evaporation, crystallization, sublimation, and filtration for example, if one component in a mixture of two solids is soluble in water, whiles a second component is not.
