The correct answer will be option b.

  • Alum is one of the oldest methods of ensuring clean drinking water. A pinch of alum added to the water removes solid impurities. Once the sediment is thrown away, the water is boiled to kill the bacteria.
  • Alum helps purify water through aluminum, which helps coagulate mud particles.
  • Due to the high charge of the aluminum ion (+3), it helps small particles in suspended solids to clump together until they are large enough to sink and be removed.
