Question

What is the chemical name of bleaching powder? How is it prepared?

Short answer

Answer: The chemical name of bleaching powder is Calcium Oxychloride (CaOCl₂). It is prepared through a chemical reaction between Calcium Hydroxide (Ca(OH)₂) and Chlorine gas (Cl₂). First, Calcium Hydroxide is formed by adding water to Calcium oxide. Then, Chlorine gas is prepared through the electrolysis of a solution of sodium chloride. Finally, Calcium Hydroxide and Chlorine gas are mixed, resulting in the formation of bleaching powder and water.

Step-by-step solution

Chemical Name of Bleaching Powder

The chemical name of bleaching powder is Calcium Oxychloride (CaOCl₂).

Preparation of Bleaching Powder

Bleaching powder is prepared through a chemical reaction between Calcium Hydroxide (Ca(OH)₂) and Chlorine gas (Cl₂). Here, we explain the step-by-step preparation process of bleaching power. Step 1: Formation of Calcium Hydroxide Calcium hydroxide is formed by adding water (H₂O) to Calcium oxide (CaO). CaO + H₂O → Ca(OH)₂ Step 2: Preparation of Chlorine gas Chlorine gas can be prepared through the electrolysis of a solution of sodium chloride (NaCl). Step 3: Reacting Calcium Hydroxide with Chlorine gas Now, we have the formation of Calcium Hydroxide and Chlorine gas. Mixing Calcium Hydroxide in the presence of an excess amount of Chlorine gas will result in the formation of bleaching powder and water. Ca(OH)₂ + 2Cl₂ → CaOCl₂ + 2H₂O This is the preparation process of bleaching powder through a chemical reaction.
