Give reason: The brown colour of an acidified dilute solution of iodine in aqueous potassium iodide is intensified by addition of nitrite but it is discharged by the addition of sulphite.

Text Solution

AI Generated Solution

To answer the question regarding the behavior of an acidified dilute solution of iodine in aqueous potassium iodide when nitrite and sulphite are added, we can break down the explanation into clear steps. ### Step-by-Step Solution: 1. **Understanding the Initial Solution**: - An acidified dilute solution of iodine in aqueous potassium iodide (KI) appears brown due to the presence of iodine (I2), which is formed from iodide ions (I⁻) in the solution. 2. **Effect of Adding Nitrite (NO2⁻)**: ...
