Charcoal is used in water treatment as a/an A. Absorbent B. Coagulant C. Solvent D. Adsorbent

The correct

Charcoal is a highly porous material that can absorb a wide range of substances, including organic matter, chemicals, and heavy metals. This makes it an effective treatment for water that is contaminated with these substances.

A coagulant is a substance that causes suspended particles in water to clump together so that they can be removed by filtration or sedimentation. A solvent is a substance that can dissolve other substances.

Charcoal is not a coagulant or a solvent. It is an absorbent.
