Current Question (ID: 9197)

Question:

$\text{Calcium hydroxide upon reacting with moist chlorine forms-}$

Options:

1. $\text{CaCl}_2$
2. $\text{Ca}(\text{OCl})_2$
3. $\text{CaCl}_2 \cdot 2\text{H}_2\text{O}$
4. $\text{CaCl}_2 \cdot 7\text{H}_2\text{O}$

Solution:

$\text{Hint: Bleaching powder is formed.}$ $\text{Explanation:}$ $\text{Chlorine reacts with freshly prepared calcium hydroxide to produce bleaching powder.}$ $2\text{Ca}(\text{OH})_2 + 2\text{Cl}_2 \rightarrow \text{CaCl}_2 + \text{Ca}(\text{OCl})_2 + 2\text{H}_2\text{O} \text{ (bleaching powder)}$ $\text{Calcium hydroxide is an odourless white powder.}$ $\text{It's used in industrial settings, such as sewage treatment, paper production, construction, and food processing.}$ $\text{Calcium hypochlorite is an inorganic compound with the formula Ca(OCl)}_2\text{.}$ $\text{It is the main active ingredient of commercial products called bleaching powder, chlorine powder, or chlorinated lime, used for water treatment and as a bleaching agent.}$
