The course explains the different types of matter present around us on the basis of chemical properties. The matter can be divided into elements , compounds and mixtures. The course explains the properties of these types of matter. It also explains the various methods that arr used for the separation of mixtures.

Learn all the basic concepts of Class IX to build a strong foundation for your future learning curve.

This lesson provides an overview of the course. The lesson explains the key features of the course and how the course can benefit the viewer. This lesson also explains the course structure of the course.

Overview of the course

This lesson explains the pure and impure substances and their classification. The lesson explains the properties of elements and the three different types of elements i.e. , metals , non-metals and metalloids are discussed in great detail.

Elements

This lesson explains the difference between homogeneous and heterogeneous mixtures. It also gives a brief introduction of compounds and differences between mixtures and compounds have also been discussed in detail. It also explains why alloys are considered a mixture.

Mixtures and Compounds

This lesson deals with the properties and classification of solutions , suspensions and colloids.

Solutions, Suspensions and Colloids

This lesson explains the percentage method of expressing the concentration of a solution. It also explains the saturated and unsaturated solutions.

Concentration of a Solution

This lesson explains the term 'solubility' in detail. The physical and chemical changes and the differences between them have also been discussed in the lesson.

Physical and Chemical Changes

This lesson explains the methods of separating a mixture of two solids by adding a suitable solvent , by the process of sublimation and by using magnet.

Separation of Mixture of Two Solids

This lesson explains the method of filtration , centrifugation and evaporation which are used for separating a mixture of a solid and a liquid.

Separation of Mixture of Solid and Liquid - Part 1

This lesson explains the method of crystallisation , chromatography and distillation which are used for separating a mixture of a solid and a liquid.

Separation of Mixture of Solid and Liquid - Part 2

This lesson explains the methods of fractional distillation and separating funnel for the separation of mixture of two or more liquids.

Separation of Mixture of Two or More Liquids

I am currently serving in BSF but I am always fond of teaching students and My son told me about this platform . So I have started teaching

Shreya Agarwal

This course is about the Matter. This course consists of detailed discussion on Mixture and it's types. It also has talks about Solutions and it's components. Further this course will have lessons on separating the components of the mixture, their physical and chemical changes followed by the Types of Pure Substances. This course will help you grasp the above mentioned topics.

Ashish Gehlot

Hello everyone this is Ashish and it is my 7th course on unacademy platform this is chapter 2 from class 9th science NCERT in this chapter we will talk about mixture, solution, suspension, colloidal solution separation of components from mixture, types of pure components, elements, compounds, physical and chemical changes and difference between compound and mixture. I have also mentioned some special separation techniques such as evaporation, centrifugation funnel, separation, simple distillation, fractional distillation, chromatography crystallization etc. in Lesson 7, I have given a question bank consisting 25 multiple choice questions related to the chapter which will ultimately brush up the concepts in the chapter. At last we will finish this chapter with summary of it in 15-20 bullet points. I hope you will like it please give a try. Each lesson is worth watching. Please do rate review the course and lessons. Also don't forget to follow me and share these lessons with your friends. Stay tuned for more search awesome courses and lessons. 
Thank you
