Correct statement(s) about hydrolysis of `H_(5)P_(3)O_(10)` is/are:

Options

A. `H_(4)P_(2)O_(6)` can be formed by its partial hydrolysis
B. Hydrolysis is proceeded by `SN_(AE)` mechanism
C. Complete hydrolysis produces `H_(3)PO_(4)`
D. `H_(5)P_(3)O_(10)` is obtained by hydrolysis of `H_(3)P_(3)O_(9)`

Explanation

To solve the question regarding the hydrolysis of \( H_5P_3O_{10} \), we will analyze the statements provided and determine their correctness based on the hydrolysis process of the compound.

### Step-by-Step Solution:

1. **Understanding Hydrolysis**:
Hydrolysis is a chemical reaction involving the breaking of a bond in a molecule using water. In this case, we are looking at the hydrolysis of \( H_5P_3O_{10} \).

2. **Identifying the Hydrolysis Products**:
When \( H_5P_3O_{10} \) undergoes hydrolysis, it can produce \( H_3PO_4 \) (phosphoric acid) and other phosphorus oxoacids. The hydrolysis process can be partial or complete.

3. **Analyzing Each Statement**:
- **Statement A**: "H4P2O6 can be found by its partial hydrolysis."
- This statement is incorrect. The partial hydrolysis of \( H_5P_3O_{10} \) produces \( H_4P_2O_7 \), not \( H_4P_2O_6 \).

- **Statement B**: "Hydrolysis proceeded by SNAE addition elimination mechanism."
- This statement is correct. The hydrolysis of \( H_5P_3O_{10} \) does proceed via the SNAE (Substitution, Addition, Elimination) mechanism.

- **Statement C**: "Complete hydrolysis produces H3PO4."
- This statement is also correct. Upon complete hydrolysis, \( H_5P_3O_{10} \) yields \( H_3PO_4 \).

- **Statement D**: "H5P3O10 is obtained by hydrolysis of H3P3O9."
- This statement is correct. \( H_5P_3O_{10} \) is indeed formed from the hydrolysis of \( H_3P_3O_9 \).

4. **Conclusion**:
Based on the analysis:
- Statement A is incorrect.
- Statements B, C, and D are correct.

### Final Answer:
The correct statements about the hydrolysis of \( H_5P_3O_{10} \) are B, C, and D.
