Statement-1 : When Na reacts with `H_2O, H_2` gas is release.
Statement-2 : `P_4O_(10)` on hydrolysis produce `H_3PO_3. `

Options

A. If both the statements are True and statement-2 is the correct explanation of statement-1
B. If both the statements are True and statement-2 is not the correct explanation of statement-1
C. If statement-1 is true and statement-2 is false
D. If statement-1 is false and statement-2 is true

Answer

To solve the question, we need to evaluate both statements provided and determine their validity.

### Step-by-Step Solution:

1. **Evaluate Statement 1**:
- The statement claims that when sodium (Na) reacts with water (H2O), hydrogen gas (H2) is released.
- The chemical reaction can be represented as:
\[ 2 \text{Na} + 2 \text{H}_2\text{O} \rightarrow 2 \text{NaOH} + \text{H}_2 \]
- In this reaction, sodium reacts with water to produce sodium hydroxide (NaOH) and hydrogen gas (H2).
- **Conclusion**: Statement 1 is true.

2. **Evaluate Statement 2**:
- The statement claims that P4O10 on hydrolysis produces H3PO3 (phosphorous acid).
- The correct reaction for the hydrolysis of P4O10 is:
\[ \text{P}_4\text{O}_{10} + 6 \text{H}_2\text{O} \rightarrow 4 \text{H}_3\text{PO}_4 \]
- This reaction indicates that P4O10 reacts with water to produce H3PO4 (orthophosphoric acid), not H3PO3.
- **Conclusion**: Statement 2 is false.

3. **Determine the Correct Option**:
- Based on the evaluations:
- Statement 1 is true.
- Statement 2 is false.
- Therefore, the correct option is:
- **Option C**: Statement 1 is true but statement 2 is false.

### Final Answer:
**Option C: Statement 1 is true but statement 2 is false.**
