Question
Explain why factory waste is neutralised before disposing it into the water bodies.
Solution
- Factory waste contains acidic substances. If such waste materials are allowed to flow into water bodies, the acidic effect of the waste can destroy fish and other aquatic life.
- Therefore, before flowing the factory waste into water bodies, it is neutralized so that there is no danger to the life forms in the water bodies.
