Current Question (ID: 9191)

Question:

$\text{An active ingredient in bleaching powder that aids in the bleaching action is:}$

Options:

1. $\text{Ca}(\text{OCl})_2$
2. $\text{CaO}_2\text{Cl}$
3. $\text{CaCl}_2$
4. $\text{CaOCl}_2$

Solution:

$\text{Hint: Calcium hypochlorite is active reagent in bleaching powder.}$ $\text{Explanation:}$ $\text{Bleaching powder is made with slightly moist slaked lime.}$ $\text{It is not a simple mixture of calcium hypochlorite, calcium chloride, and calcium hydroxide.}$ $\text{Instead, it is a mixture consisting principally of calcium hypochlorite Ca(OCl)}_2\text{, dibasic calcium hypochlorite, Ca}_3\text{(OCl)}_2\text{(OH)}_4\text{ (also written as Ca(OCl)}_2 \cdot 2\text{Ca(OH)}_2\text{), and dibasic calcium chloride, Ca}_3\text{Cl}_2\text{(OH)}_4\text{ (calcium hydroxychloride also written as CaCl}_2 \cdot 2\text{Ca(OH)}_2\text{)}$ $\text{But, Ca(OCl)}_2\text{, Calcium hypochlorite is present as an active ingredient in bleaching powder for bleaching action and releases chlorine.}$
