Select the correct statement(s):

Options

A. All carbonate salt are soluble except carbonate salt alkline metals and `(NH_(4))_(2)CO_(3)`
B. All carbonate salt are soluble except `NaHCO_(3)` white is sparingly soluble
C. All sulphite salt are insoluble excess sulphate salts is alkline metal and `(NH_(4))_(2) SO_(3)`
D. All `MnO_(4)^(Θ)` salt are insoluble

Answer

To solve the question regarding the correct statements about the solubility of various salts, we will analyze each statement one by one:

### Step-by-Step Solution:

1. **Analyzing Statement A**:
- Statement: "All carbonate salts are soluble except carbonate salts of alkaline metals and ammonium carbonate."
- Analysis: This statement is incorrect because ammonium carbonate is soluble in water. The alkaline earth metal carbonates (like calcium carbonate, magnesium carbonate) are generally insoluble, but ammonium carbonate is an exception. Therefore, Statement A is **wrong**.

2. **Analyzing Statement B**:
- Statement: "All carbonates are soluble except sodium bicarbonate which is sparingly soluble."
- Analysis: This statement is also incorrect. The correct statement should be that all bicarbonate salts are soluble except sodium bicarbonate, which is sparingly soluble due to its high lattice energy. Therefore, Statement B is **correct**.

3. **Analyzing Statement C**:
- Statement: "All sulfide salts are insoluble except sulfide salts of alkaline metals and ammonium sulfide."
- Analysis: This statement is incorrect. While it is true that most sulfides are insoluble, the alkaline metal sulfides (like sodium sulfide, potassium sulfide) are soluble. However, the statement incorrectly implies that all sulfides are insoluble, which is not true. Therefore, Statement C is **wrong**.

4. **Analyzing Statement D**:
- Statement: "All MnO4^- salts are insoluble."
- Analysis: This statement is incorrect. For example, potassium permanganate (KMnO4) is a MnO4^- salt and is highly soluble in water. Therefore, Statement D is **wrong**.

### Conclusion:
Based on the analysis above, the only correct statement is Statement B.

### Final Answer:
The correct option is **B**: "All bicarbonate salts are soluble except sodium bicarbonate which is sparingly soluble."
