Both the assertion and the reason are true is the correct answer to the given question.

  • As we know that bleaching powder is prepared on a large scale by passing chlorine gas through a solution of calcium hydroxide\left(\mathrm{Ca}(\mathrm{OH})_{2}\right) which is commonly called slaked lime.
  • \text { The reaction that occurs is } \mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{Cl}_{2}(\mathrm{~g}) \rightarrow \mathrm{CaOCl}_{2}+\mathrm{H}_{2} \mathrm{O} \text {. }
  • Hence, bleaching powder is mainly used for bleaching papers and sterilizing water.
