Statement-1: When `H_(2)S` gas is passed through Na-nitroprusside solution it gives purple colouration.
Statement-2: `H_(2)S` is an weal acid.

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-49
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To analyze the statements provided in the question, we will evaluate each statement one by one.

### Step 1: Evaluate Statement-1
**Statement-1**: When `H₂S` gas is passed through Na-nitroprusside solution, it gives purple coloration.

- **Analysis**: Sodium nitroprusside is represented as Na₂[Fe(CN)₅NO]. When hydrogen sulfide (H₂S) is introduced to this solution, it reacts with the nitroprusside. However, the expected reaction does not produce a purple coloration. Instead, the presence of H₂S leads to the formation of a different compound that does not exhibit the characteristic purple color associated with sodium nitroprusside. Therefore, this statement is incorrect.

### Step 2: Evaluate Statement-2
**Statement-2**: `H₂S` is a weak acid.

- **Analysis**: Hydrogen sulfide (H₂S) can indeed act as a weak acid. It partially dissociates in water to release hydrogen ions (H⁺), which is characteristic of acids. The pKa value of H₂S is around 7, indicating that it is a weak acid. Therefore, this statement is correct.

### Conclusion
- **Statement-1** is incorrect.
- **Statement-2** is correct.

### Final Answer
Both statements cannot be true simultaneously. Therefore, the answer to the question is that Statement-1 is false, and Statement-2 is true.
