Model Answer

Two uses of bleaching powder are:

  1. It is used for disinfecting drinking water to make it free from germs.
  2. It is used as an oxidising agent in chemical industries and for bleaching cotton and linen in the textile industry.
Explanation

Bleaching powder (Ca(OCl)Cl) is a key topic from the chapter on Acids, Bases and Salts. Examiners expect any two distinct, correct uses. Common acceptable uses include: disinfecting water, bleaching cotton/linen/wood pulp, as an oxidising agent, and for making wool unshrinkable. Write two clearly separate points for full 2-mark credit. Note: the source passages provided do not cover bleaching powder directly — this answer is based on the standard NCERT Class 10 Science Chapter 2 content on bleaching powder.
