Statement 1: Ammonium phosphomolybdate is a yellow compound.
Statement 2: If yellow precipitate is obtained on adding ammonium molybdate solution on boiling then phosphate radical is identified.

Options

A. Statement 1 is true, statement 2 is true, statement 2 is a correct explanation for statement 1
B. Statement 1 is true, statement 2 is true, statement 2 is not a correct explanation for statement 1
C. Statement 1 is true, statement 2 is false
D. Statement 1 is false, statement 2 is true

Explanation

To solve the question regarding the two statements about ammonium phosphomolybdate and its identification of phosphate radicals, we will analyze both statements step by step.

### Step-by-Step Solution:

1. **Understanding Statement 1**:
- The first statement claims that ammonium phosphomolybdate is a yellow compound.
- Ammonium phosphomolybdate is indeed known to form a yellow precipitate when phosphate ions are present. This is a characteristic feature of this compound.

2. **Understanding Statement 2**:
- The second statement indicates that if a yellow precipitate is obtained upon adding ammonium molybdate solution and boiling, then the phosphate radical is identified.
- When ammonium molybdate is added to a solution containing phosphate ions (PO4^3-), a yellow precipitate of ammonium phosphomolybdate forms. This confirms the presence of the phosphate radical.

3. **Analyzing the Relationship Between the Statements**:
- The first statement is true because ammonium phosphomolybdate is indeed a yellow compound.
- The second statement is also true as it explains how the presence of the yellow precipitate indicates the identification of the phosphate radical.

4. **Conclusion**:
- Both statements are true, and the second statement serves as a correct explanation for the first statement. Therefore, the correct answer is that both statements are true, and the second statement is the correct explanation for the first.

### Final Answer:
Both Statement 1 and Statement 2 are true, and Statement 2 is the correct explanation for Statement 1.
