Q104 / 200 · NEET 2011 (Screening) · Physics

Which one of the following is present as an active ingredient in bleaching powder for bleaching action?

Correct answer
A
$\mathrm{Ca}(\mathrm{OCl})_2$
B
$\mathrm{CaO}_2 \mathrm{Cl}$
C
$\mathrm{CaCl}_2$
D
$\mathrm{CaOCl}_2$

Solution

$\mathrm{Ca}(\mathrm{OCl})_2$, calcium hypochlorite is the active ingredient in beleaching powder which releases chlorine.
