Current Question (ID: 8615)

Question:

$\text{In the given reaction, what is the name of the species that bleaches the substances due to its oxidising action?}$ $\text{Cl}_2\text{(g)} + 2\text{OH}^-\text{(aq)} \rightarrow \text{ClO}^-\text{(aq)} + \text{Cl}^-\text{(aq)} + \text{H}_2\text{O}\text{(l)}$

Options:

1. $\text{ClO}^-$
2. $\text{Cl}_2$
3. $\text{Cl}^-$
4. $\text{Both ClO}^- \text{ and Cl}^-$

Solution:

$\text{Hint: Concept of a disproportionation reaction}$ $\text{Explanation:}$ $\text{Step 1:}$ $\text{Cl}_2\text{(g)} + 2\text{OH}^-\text{(aq)} \rightarrow \text{ClO}^-\text{(aq)} + \text{Cl}^-\text{(aq)} + \text{H}_2\text{O}\text{(l)}$ $\text{In this reaction, O.N. of Cl increases from 0 (in Cl}_2\text{) to +1 (in ClO}^-\text{) as well as decreases from 0 (in Cl}_2\text{) to -1 (in Cl}^-\text{). So, it acts as both a reducing as well as an oxidizing agent.}$ $\text{Step 2:}$ $\text{This is an example of a disproportionation reaction. In this reaction, ClO}^- \text{ species bleaches the substances due to its oxidizing action. [In hypochlorite ion (ClO}^-\text{) Cl can decrease its oxidation number from +1 to 0 or -1.]}$ $\text{The correct answer is ClO}^-$
