Which of the following chloride is water insoluble

Options

A. HCl
B. AgCl
C. Both (a) and (b)
D. None of these

Explanation

To determine which chloride is water insoluble, we can analyze the solubility of different chlorides based on their polarity and the nature of the ions involved.

### Step-by-Step Solution:

1. **Understand the Nature of Water**:
- Water (H₂O) is a polar solvent. This means it has a partial positive charge on one side (hydrogens) and a partial negative charge on the other side (oxygen). Polar substances tend to dissolve well in polar solvents.

2. **Identify the Chlorides**:
- The question asks about the solubility of various chlorides. Common examples include HCl (hydrochloric acid) and AgCl (silver chloride).

3. **Analyze HCl**:
- HCl is a strong acid and is highly soluble in water. This is because it is polar and can interact effectively with the polar water molecules. Thus, HCl will dissolve readily in water.

4. **Analyze AgCl**:
- AgCl, on the other hand, is known to be insoluble in water. The reason for this is that Ag⁺ (silver ion) has a relatively large size compared to other cations, leading to a non-polar characteristic when paired with Cl⁻ (chloride ion). The interactions between AgCl and water are not favorable, resulting in its insolubility.

5. **Conclusion**:
- Based on the analysis, AgCl is the chloride that is water insoluble.

### Final Answer:
AgCl (silver chloride) is water insoluble.
