1.0NCERT Solutions Class 6 science chapter 3 Separation of substances: Points to Remember

Understanding the concepts below will prepare you well for the Class 6 Science Chapter 3 on Separation of Substances.

1. Mixture:

A substance comprises two or more different kinds of matter mixed but not chemically combined.

Types of Mixtures:

• Homogeneous Mixture: A mixture that has a uniform composition throughout. Example: Saltwater, air.
• Heterogeneous Mixture: A mixture that does not have a uniform composition. Example: Soil, salad.

2. Methods of Separation:

• Handpicking: Separating larger objects by hand.
• Threshing: Separating grains from stalks by beating.
• Winnowing: Separating lighter particles from heavier ones using wind.
• Sieving: Separating particles based on size using a sieve.
• Sedimentation: Allowing solid particles to settle at the bottom of a liquid.
• Decantation: Carefully pour off the clear liquid from a mixture after sedimentation.
• Filtration: Separating solids from liquids using filter paper.
• Evaporation: Separating a dissolved solid from a liquid by heating.
• Magnetic Separation: Separating magnetic materials from non-magnetic ones using a magnet.

3. Other Important Concepts:

• Insoluble: A substance that does not dissolve in a particular solvent (e.g., sand in water).
• Soluble: A substance dissolves in a specific solvent (e.g., salt in water).
• Residue: The solid substance left behind on the filter paper after filtration.
• Filtrate: The liquid that passes through the filter paper during filtration.
