Number of electrons involved in the reaction when 0.1 mol `NH_(3)` dissolved in water

Options

A. 2
B. 0.4
C. 0.9
D. Zero

Answer

To solve the question regarding the number of electrons involved when 0.1 mol of NH₃ is dissolved in water, we can follow these steps:

### Step 1: Understand the Reaction
When ammonia (NH₃) is dissolved in water, it undergoes a reaction to form ammonium hydroxide (NH₄OH). The reaction can be represented as:

\[ \text{NH}_3 (aq) + \text{H}_2\text{O} (l) \rightarrow \text{NH}_4\text{OH} (aq) \]

### Step 2: Identify the Nature of the Reaction
This reaction is not a redox reaction. In a redox reaction, there is a transfer of electrons between species, leading to changes in oxidation states. However, in this case, NH₃ simply interacts with water to form NH₄OH without any change in oxidation states.

### Step 3: Analyze Electron Transfer
Since there is no change in oxidation states and no transfer of electrons occurs during the dissolution of NH₃ in water, we conclude that:

- **Number of electrons involved = 0**

### Conclusion
Thus, the number of electrons involved when 0.1 mol of NH₃ is dissolved in water is **0**.

### Final Answer
The correct option is **0 electrons** involved in the reaction.
