Question

Why do we need to separate substances?

Answer 1

The need for separation of substances from mixtures is:

• Separation of the constituents of a mixture helps us to recover a useful component. Example: Separation of grains from husk.
• An appropriate process of separation may be used to eliminate harmful or undesirable components from a mixture. Example: Separation of stones from rice.
• The properties of a mixture can sometimes be studied better once the constituents are separated from each other and understood individually.
