The video discusses various separation techniques based on physical properties like particle size and density to separate mixtures into their components. Techniques such as sieving, sedimentation, decantation, centrifugation, and separation funnels are explained with practical examples.
Separation Techniques Based on Particle Size and Density
Concepts covered:mixtures, separation techniques, particle size, density, physical changes
The chapter discusses the physical separation of mixtures based on differences in particle size and density, emphasizing the use of techniques like sieving. Physical changes in mixtures involve alterations in their physical properties without affecting their chemical composition.
