Which of the following ppt , is soluble dil , `HNO_(3)`and `NH_(3)` solution ?

Options

A. `Ag_(2)S_(2)O_(3)`
B. `Ag_(2)CO_(3)`
C. `Ag_(2)SO_(3)`
D. `AgI`

Answer

To determine which of the following precipitates (ppt) are soluble in dilute HNO3 and NH3 solution, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Silver Salts**: The question revolves around silver salts, particularly looking for those that are soluble in dilute nitric acid (HNO3) and ammonia (NH3).

2. **Understand Solubility Rules**:
- All silver salts are soluble in dilute HNO3 and NH3, except for silver halides.
- Among silver halides, AgCl and AgBr are partially soluble in NH3, while AgI is insoluble in both dilute HNO3 and NH3.

3. **List the Silver Salts**: The silver salts we need to consider include:
- Silver thiosulfate (Ag2S2O3)
- Silver chromate (Ag2CrO4)
- Silver sulfide (Ag2S)
- Silver halides (AgCl, AgBr, AgI)

4. **Check Solubility in HNO3 and NH3**:
- **Silver thiosulfate**: Soluble in dilute HNO3 and NH3.
- **Silver chromate**: Soluble in dilute HNO3 and NH3.
- **Silver sulfide**: Soluble in dilute HNO3 and NH3.
- **Silver chloride (AgCl)**: Soluble in NH3 but not in HNO3.
- **Silver bromide (AgBr)**: Partially soluble in NH3 but not in HNO3.
- **Silver iodide (AgI)**: Insoluble in both HNO3 and NH3.

5. **Conclusion**: The silver salts that are soluble in both dilute HNO3 and NH3 are:
- Silver thiosulfate (Ag2S2O3)
- Silver chromate (Ag2CrO4)
- Silver sulfide (Ag2S)

### Final Answer:
The precipitates that are soluble in dilute HNO3 and NH3 solution are:
- Silver thiosulfate (Ag2S2O3)
- Silver chromate (Ag2CrO4)
- Silver sulfide (Ag2S)
