Answer 2

Answer:

Explanation:

Because it is an oxidizing agent and combines with CO2 outdoors to produce chlorine gas with a strong aroma, the supplied compound "A" is calcium oxychloride.

• CaOCl2 + CO2  → CaCO3 + Cl2

Dry slaked lime and chlorine gas are used to prepare it.

• Ca(OH)2 + Cl2 →  CaOCl2 + H2O

Bleaching powder is the brand name for calcium oxychloride in commerce.

Reason for bleaching action of chlorine:

Hydrochloric acid is created when chlorine combines with water. This unstable acid soon dissociates to produce nascent oxygen. A more potent oxidizing agent is nascent oxygen. Thus, chlorine's bleaching properties in the presence of moisture are caused by the creation of nascent oxygen.

• 3Cl2 + 6NAOH → 5Nacl + Naclo3 + 3H2O
