Bleaching powder can be obtained by which of the following reactions?
- A \(\mathrm{Mg}(\mathrm{OH})_2+\mathrm{F}_2 \xrightarrow{\Delta} \mathrm{MgOF}_2+\mathrm{H}_2 \mathrm{O}\)
- B \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \xrightarrow{\Delta} \mathrm{CaOCl}_2+\mathrm{H}_2 \mathrm{O}\)
- C \(\mathrm{Ba}(\mathrm{OH})_2+\mathrm{Br}_2 \xrightarrow{\Delta} \mathrm{BaOBr}_2+\mathrm{H}_2 \mathrm{O}\)
- D \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{F}_2 \xrightarrow{\Delta} \mathrm{CaOF}_2+\mathrm{H}_2 \mathrm{O}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \xrightarrow{\Delta} \mathrm{CaOCl}_2+\mathrm{H}_2 \mathrm{O}\)
Step-by-step Solution
Detailed explanation
The chemical formula of bleaching powder is \(\mathrm{CaOCl}_2\), so the correct reaction is \(\mathrm{Ca}(\mathrm{OH})_2+\mathrm{Cl}_2 \stackrel{\Delta}{\longrightarrow} \mathrm{CaOCl}_2+\mathrm{H}_2 \mathrm{O}\)
