Why factory waste should be neutralized before disposing it into the water bodies?
Fudgin [204]

Explanation:

Factory wastes are usually acidic and they pose serious environmental challenges.

If an untreated acidic waste is discharged into the river, the acidity of the river increases and this is toxic to life in the water.

On land, the acid can enter into the soil and prevent plant growth.

Acid discharge can enter the groundwater system and render it unfit for use.

Bases and a couple of additives are used to remove acidity from factory wastes before they are discharged.
