The bleaching action of bleaching powder is due to the formation of:
Correct answer: C. HClO
- A. CaCl2
- B. CaSO4
- C. HClO
- D. Ca(ClO3)2
Explanation
The correct answer is HClO. The bleaching action of bleaching powder is due to the formation of hypochlorous acid (HClO). In the presence of dilute acids, bleaching powder loses oxygen, which is used for oxidation and bleaching. The other options (CaCl2, CaSO4, Ca(ClO3)2) are incorrect as they do not play a role in the bleaching action of bleaching powder.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
