Current Question (ID: 9192)

Question:

$\text{The bleaching action of bleaching powder is due to the formation of :}$

Options:

1. $\text{OCl}^-$
2. $\text{O}_2$
3. $\text{Cl}_2$
4. $\text{Cl}^-$

Solution:

$\text{Hint: Nascent oxygen is produced.}$ $\text{Explanation:}$ $\text{The bleaching powder has a strong bleaching action due to the formation of nascent oxygen.}$ $\text{When bleaching powder reacts with a small amount of acid, it gives nascent oxygen.}$ $\text{Thus, it acts as an oxidizing agent and thus acts as a bleaching agent.}$ $2\text{Ca}(\text{OCl})_2 + \text{H}_2\text{SO}_4 \rightarrow \text{CaCl}_2 + \text{CaSO}_4 + 2\text{HOCl}$ $2\text{HOCl} \rightarrow 2\text{HCl} + 2[\text{O}]$
