Why is it necessary to separate the components of a mixture ? Explain.
Answer
It is necessary to separate the components of a mixture for the following reasons:
To Obtain Useful Substances: Some mixtures contain valuable substances that can be separated and used for various purposes. For example, when crude petroleum is separated, we obtain useful substances like LPG, CNG, petrol, diesel, and kerosene oil, which are primarily used as fuels.
To Remove Unwanted and Harmful Substances: Mixtures may contain impurities or harmful substances that can be harmful to health or degrade the quality of the product. For example, small stones and husk need to be removed from cereals like rice, wheat, and pulses before cooking because they are harmful.
To Obtain Pure Substances for Preparing Other Useful Substances: Sometimes, it is important to separate unwanted components to obtain a pure substance for specific purposes. For instance, drinking water contains air and mineral salts, which need to be removed to obtain pure water for laboratory use, medicine preparation, or for use in car batteries.
Hence, separating the components of a mixture ensures we obtain useful, pure substances and remove harmful or unnecessary impurities.
