Phosphorus trichloride, `PCl_(3)` undergoes, hydrolysis at room temperature to produce an oxoacid. It has the formula :

Options

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

Answer

To solve the question regarding the hydrolysis of phosphorus trichloride (PCl₃) and the oxoacid produced, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**:
Phosphorus trichloride (PCl₃) reacts with water (H₂O) during hydrolysis.

2. **Write the Hydrolysis Reaction**:
The hydrolysis of PCl₃ can be represented as:
\[ PCl_3 + 3H_2O \rightarrow H_3PO_3 + 3HCl \]
Here, PCl₃ reacts with three molecules of water.

3. **Identify the Products**:
From the reaction, we can see that the products are:
- Phosphorous acid (H₃PO₃), which is the oxoacid we are looking for.
- Hydrochloric acid (HCl).

4. **Conclusion**:
The oxoacid produced from the hydrolysis of phosphorus trichloride (PCl₃) is phosphorous acid, which has the formula H₃PO₃.

### Final Answer:
The formula of the oxoacid produced is **H₃PO₃**.
