Separation of Mixtures Using Different Techniques (Theory

How Is A Homogeneous Mixture Different from A Heterogeneous mixture?What Are Types of Separation Techniques?Let’s Discuss Some of The Separation TechniquesMost materials in our surroundings are mixtures of two or more components. Mixtures are either homogeneous or heterogeneous. Homogeneous mixtures are uniform in composition, but heterogeneous mixtures are not uniform in composition.Air is a homogeneous mixture and oil in water is a heterogeneous mixture. Homogeneous and heterogeneous mixtures can be separated into their components by several physical methods. The cho of separation techniques is based on the type of

Centrifugation - Wikipedia

Centrifugation is a technique which involves the application of centrifugal force to separate particles from a solution according to their size, shape, density, viscosity of the medium and rotor speed. Not only is this process used to separate two miscible substances, but also to analyze the hydrodynamic properties of macromolecules. More-dense components of the mixture migrate away from the

How can we separate cream from milk? NCERT Class IX

Thank you for the question! The best way to separate cream from the milk is through the process of centrifugation. The sample milk is rotated into the centrifuge.At very high speed.In this way the denser particles settles at the bottom and the lighter ones float over the surface and cream being lighter than milk will float on the top and can be easily extracted out of the milk and can be
