Question

Chlorine gas reacts with bleaching powder to form

• A. Dry slaked lime
• B. Dilute solution of Ca (OH) 2
• C. Concentrated solution of Ca (OH) 2
• D. Dry CaO

Answer 1

Answer:

A. Dry slaked lime

• Bleaching powder is manufactured by treating dry slaked lime with chlorine gas .

• Ca(OH)₂+Cl₂------->CaOCl₂+H₂O

• The slaked lime must be dry; moisture or solutions lead to different side products instead of standard bleaching powder.

• Bleaching powder is a white powder that smells like chlorine. It is also called chloride of lime, or chlorinated lime.

• Bleaching powder is soluble in water.
