Question

4. Why do we need to separate mixtures?

Answer 1

The reasons for which we need to separate mixtures are the following:

• Different components of a mixture are separated in order to either separate the un-required components from a mixture.
• To separate more than one useful component from a mixture.
• To obtain pure substances.
• For example, grain purchased from shops can contain several impurities such as pieces of stone, husk, broken grains, etc.
