Question

93. How can we separate impurities present in water?

Answer 1

• The size of the impurities is a major factor in the separation of impurities present in water.
• If the large-sized heavy impurities are present then allow the large contaminants to settle before pouring the water into another container. This is an example of the decantation process.
• If the impurity is tiny, use filter paper to filter it out, this is an example of a filtration method, or just evaporate the water first and then condense it to produce the purest form of water, this is an example of the evaporation process.
