Question

Bleaching powder is a mixed salt. In the presence of $COCl _{2}$, bleaching powder decomposes to give $CaCl _{2}$ and $O _{2}$.

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion
• B. If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion
• C. If Assertion is true but Reason is false
• D. If both Assertion and Reason are false

Answer 1

Answer: (B)

If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion

Answer 2

Bleaching powder is a mixed salt of calcium hypochlorite $\left[ Ca ( ClO )_{2}\right]$, calcium chloride, $CaCl _{2}$ and calcium hydroxide $\left[ Ca ( OH )_{2}\right]$. In presence of cobalt chloride, it decomposes into $CaCl _{2}+ O _{2} .$
