Answer 2

❒ The correct answer is:

Bleaching powder (A)

Lime water is formed when Quick lime reacts with water. It is also known as Slaked lime, and chemically Calcium Hydroxide {$\sf{Ca(OH)_2}$}.Chlorine gas is released during the electrolysis of Brine solution(Aqueous solution of Sodium chloride). This Chlorine is used along with Lime water to form a very useful salt, Bleaching powder.

• Bleaching powder is produced when Dry Slaked lime reacts with Clorine gas. The reaction is:

$\large{\boxed{\boxed{ \sf{Ca(OH)_2 + Cl_2 \longrightarrow CaOCl_2 + H_2O}}}}$

• CaOCl2 is Bleaching powder in short because actually, the composition is little bit complex.
• Chemically, CaOCl2 is Calcium Oxychloride.

☯️ Do you know? When Bleaching powder is produced at large scale in factories and industries, The plant used for it is known as "Hasenclver's plant"
