Select the correct statement?

Options

A. Milk is an emulsion of water in fat
B. Clay may be peptised by alkalis, the OH- being the active agent
C. Both (1) and (2)
D. None of these

Answer

To solve the question, we need to analyze the statements provided and determine which one is correct.

### Step-by-Step Solution:

1. **Understanding Emulsions**:
- An emulsion is a mixture of two immiscible liquids where one liquid is dispersed in the other. Common types include oil-in-water (O/W) and water-in-oil (W/O).
- In the context of milk, it is often referred to as an emulsion of fat in water (O/W), meaning fat droplets are dispersed in water.

2. **Analyzing the First Statement**:
- The statement claims: "Milk is an emulsion of water in fat."
- This is incorrect because milk is actually an emulsion of fat in water (O/W), not water in fat (W/O).

3. **Analyzing the Second Statement**:
- The statement claims: "Clay may be peptized by alkali, the OH- being the active reagent."
- Peptization refers to the process of converting a coagulated sol into a stable colloidal solution. Alkali can indeed peptize clay, but the explanation provided in the transcript suggests that the negative charge on clay particles would not be affected by OH- ions. This reasoning is flawed because OH- can interact with the clay particles to help stabilize them.

4. **Conclusion**:
- Both statements provided in the question are incorrect based on the analysis above. Therefore, if the question asks to select the correct statement, the answer would be that none of the statements are correct.

### Final Answer:
None of the statements provided are correct.
