Answer:
Q1. An impure substance is made of two or more elements or compounds that are not bonded together chemically.
Q2. Mixtures of solids may be separated by differing solubilities of the solids.
Components of a solution composed of a non-volatile solid solute and a liquid solvent can be separated by distillation.
Mixtures of liquids with reasonably different boiling points can also be separated by distillation.
Q3. There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures.
Q4. A homogenous mixture is that mixture in which the components mix with each other and its composition is uniform throughout the solution.
A heterogenous mixture is that mixture in which the composition is not uniform throughout and different components are observed.
Q5. We need to separate different components of a mixture:
1. To separate harmful or non - useful substances that may be mixed with it.
2. To separate even useful components if we need to use them separately.
Examples:
∙ Milk or curd is churned to separate the butter.
∙ Grain is separated from stalks, while harvesting.
Q6. The process used to separate butter, curd, or cream from milk is churning or centrifugation. Centrifugation is a method for separating the suspended particles of a substance from a liquid in which the mixture is rotated at a high speed in a centrifuge machine.
