The final product formed , when alkaline Kl solution reacts with ozone and water is

Options

A. `l_(2)`
B. `KlO_(3)`
C. `Hl`
D. Reaction will not occur

Answer

To solve the question regarding the final product formed when alkaline KI solution reacts with ozone and water, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in this reaction are alkaline potassium iodide (KI) solution, ozone (O3), and water (H2O).

2. **Understand the Role of Ozone**: Ozone is a strong oxidizing agent. In this reaction, it will oxidize potassium iodide (KI).

3. **Write the Reaction**: The reaction can be summarized as:
\[ \text{O}_3 + \text{KI} + \text{H}_2\text{O} \rightarrow \text{I}_2 + \text{O}_2 + \text{KOH} \]
Here, ozone oxidizes iodide ions (I-) from potassium iodide to form iodine (I2).

4. **Identify the Products**: The products of this reaction are:
- Iodine (I2)
- Oxygen gas (O2)
- Potassium hydroxide (KOH)

5. **Determine the Final Product**: Since the question asks for the final product formed, we focus on the main product of interest, which is iodine (I2).

6. **Conclusion**: Therefore, the final product formed when alkaline KI solution reacts with ozone and water is iodine (I2).

### Final Answer:
The final product formed is **I2** (iodine).
