Question

Why
is it wise to neutralise the factory wastes before disposing off them into rivers and lakes ?​

Answer 1

Answer:

Factory wastes contain acids which if untreated and discharged into water bodies will cause harm to fish and other aquatic organisms living in water bodies. Therefore, they should first be treated with basic substances to neutralise them and then discharged into water bodies.

Answer 2

Answer:

it is because untreated and acidic / basic wastes can cause environmental pollution .

this is of serious concern .

if the wastes are thrown in the water , the aquatic organisms would die .

if the wastes are thrown in land , the land would become uncultivable .

if the wastes are thrown in the air , the air would become polluted .

hence it is wise to neutralise factory wastes before disposal .
