Welcome to the course on the "Separation Of Mixtures And Purification Of Chemicals." This course will delve into the fundamental concepts and techniques involved in separating mixtures into their individual components and purifying chemicals to obtain desired substances of high purity.

Firstly, we will explore the distinction between pure and impure substances. A pure substance consists of only one type of compound or element, while an impure substance contains more than one type of compound or element. The purity of a substance can be evaluated based on its boiling and melting points. Impurities tend to lower and broaden the melting and boiling points of substances.

Next, we will differentiate between elements, compounds, and mixtures. Elements are substances made up of only one type of atom, compounds are substances composed of two or more elements in fixed ratios, and mixtures are combinations of two or more substances that are not chemically combined.

Furthermore, we will discuss the dissimilarities between chemical and physical changes. Chemical changes result in the formation of new substances with different chemical properties, while physical changes do not alter the chemical composition of substances.

As we progress, we will identify the properties of the components of a mixture, which will aid in selecting appropriate separation techniques. Various separation processes such as evaporation, simple and fractional distillation, sublimation, filtration, crystallization, paper and column chromatography, simple and fractional crystallization, magnetization, and decantation will be explored in detail.

Moreover, we will specify the principles involved in each separation method. For instance, distillation relies on the differences in boiling points of components, while chromatography exploits varying affinities of substances for the stationary and mobile phases.

Finally, we will apply the basic principles of separation processes in everyday life scenarios. Understanding these techniques is crucial for various industries, laboratories, and even household activities where separation and purification are essential for obtaining specific substances.
