Question

Why do we need to separate different components of a mixture? Give two examples.​

Answer 1

We need to separate different components of a mixture to:​

• Obtain useful components. For example, salt is obtained from salty sea water by evaporation.
• Remove undesirable components. For example, tea leaves are separated from the liquid tea using a strainer.
• Separate impurities or harmful components. For example, stones and pebbles are handpicked and separated from pulses and grains before cooking.
