The phosphorous containing compound produced in the reaction of `H_(2)SO_(4)` with `P_(2)O_(5)` is

Options

A. `HPO_(3)`
B. `H_(3)PO_(2)`
C. `H_(3)PO_(4)`
D. `H_(3)PO_(5)`

Answer

To determine the phosphorus-containing compound produced when sulfuric acid (H₂SO₄) reacts with phosphorus pentoxide (P₂O₅), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are sulfuric acid (H₂SO₄) and phosphorus pentoxide (P₂O₅).

### Step 2: Write the Reaction
When H₂SO₄ reacts with P₂O₅, the reaction can be represented as:
\[ \text{H}_2\text{SO}_4 + \text{P}_2\text{O}_5 \rightarrow \text{SO}_3 + \text{HPO}_3 \]

### Step 3: Identify the Products
From the reaction, we can see that sulfur trioxide (SO₃) and metaphosphoric acid (HPO₃) are produced.

### Step 4: Determine the Phosphorus-Containing Compound
The phosphorus-containing compound produced in this reaction is metaphosphoric acid, which is represented by the formula HPO₃.

### Conclusion
The correct answer to the question is:
**HPO₃ (metaphosphoric acid)**.
