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.
