Which of the following statements is correct for a lyophobic solution ?

Options

A. It can be easily solvated
B. It carries charges
C. The coagulation of this sol is irreversible in nature
D. It is less stable in a solvent

Explanation

To determine which statement is correct for a lyophobic solution, we need to understand the characteristics of lyophobic solutions. Here’s a step-by-step breakdown of the solution:

### Step 1: Define Lyophobic Solutions
Lyophobic solutions are colloidal systems where the dispersed phase (the solute) does not have a strong affinity for the dispersion medium (the solvent). This means that the interaction between the dispersed phase and the dispersion medium is minimal.

**Hint:** Remember that "lyophobic" translates to "solvent-hating," indicating weak interactions with the solvent.

### Step 2: Characteristics of Lyophobic Solutions
1. **Interaction**: There is little to no interaction between the dispersed phase and the dispersion medium.
2. **Charge**: The particles in a lyophobic solution often carry a charge, which can lead to stability issues.
3. **Coagulation**: The coagulation (or aggregation) of these solutions is typically irreversible, meaning once they aggregate, they cannot easily be dispersed again.
4. **Stability**: Lyophobic solutions are generally less stable in the solvent compared to lyophilic solutions.

**Hint:** Focus on the stability and interaction aspects when considering the characteristics of lyophobic solutions.

### Step 3: Evaluate the Given Statements
Now, let’s evaluate the options provided (A, B, C, D) based on the characteristics discussed:

- **Option A**: "It can be easily solvated."
- This is incorrect because lyophobic solutions do not interact well with the solvent, making solvation difficult.

- **Option B**: "They carry charges."
- This is correct as lyophobic particles often carry charges which can affect their stability.

- **Option C**: "Coagulation is irreversible."
- This is also correct; once coagulated, lyophobic solutions do not easily return to their dispersed state.

- **Option D**: "They are less stable in solvent."
- This statement is correct as well; lyophobic solutions are indeed less stable compared to lyophilic solutions.

### Conclusion
Based on the analysis, the correct statements regarding lyophobic solutions are B, C, and D.

**Final Answer**: Options B, C, and D are correct for a lyophobic solution.
