When `NH_(3)` reacts with conc. `H_(2)SO_(4)` products formed is/are:

Options

A. `(NH_(4))_(2)SO_(4)`
B. `SO_(2)`
C. `SO_(3)`
D. `NH_(4)OH`

Answer

To determine the products formed when ammonia (NH₃) reacts with concentrated sulfuric acid (H₂SO₄), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are ammonia (NH₃) and concentrated sulfuric acid (H₂SO₄).

### Step 2: Understand the Nature of the Reaction
Ammonia is a basic compound, and sulfuric acid is a strong acid. When they react, we can expect a neutralization reaction to occur, leading to the formation of an ammonium salt.

### Step 3: Write the Reaction
The reaction can be represented as follows:
\[ \text{NH}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{NH}_4\text{HSO}_4 \]
However, in the presence of excess ammonia, the reaction can further yield ammonium sulfate:
\[ 2 \text{NH}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{(NH}_4\text{)}_2\text{SO}_4 \]

### Step 4: Identify the Product
The main product formed from the reaction of ammonia with concentrated sulfuric acid is ammonium sulfate, which has the formula:
\[ \text{(NH}_4\text{)}_2\text{SO}_4 \]

### Step 5: Conclusion
Thus, the product formed when ammonia reacts with concentrated sulfuric acid is ammonium sulfate, represented as:
\[ \text{(NH}_4\text{)}_2\text{SO}_4 \]

### Final Answer
The correct answer is ammonium sulfate, \((\text{NH}_4)_2\text{SO}_4\).
