C. for clear/colourless solution
D. For white ppt.

Answer

To solve the question regarding the reaction between ZnSO₄ solution and MgCl₂ solution, we need to analyze the compounds involved and determine why no reaction occurs. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants given are Zinc sulfate (ZnSO₄) and Magnesium chloride (MgCl₂).

2. **Understand the Nature of the Compounds**:
- ZnSO₄ is a salt formed from zinc and sulfuric acid, while MgCl₂ is a salt formed from magnesium and hydrochloric acid. Both are soluble in water.

3. **Check for Possible Reactions**:
- When two ionic compounds are mixed in solution, a reaction may occur if there is a formation of an insoluble product (precipitate), a gas, or a weak electrolyte.
- The possible products of the reaction between ZnSO₄ and MgCl₂ could be magnesium sulfate (MgSO₄) and zinc chloride (ZnCl₂).

4. **Solubility Rules**:
- According to solubility rules, both MgSO₄ and ZnCl₂ are soluble in water. Therefore, no precipitate will form when these two solutions are mixed.

5. **Conclusion on Reaction**:
- Since no precipitate forms and all products remain dissolved in solution, we conclude that there is no reaction between ZnSO₄ and MgCl₂.

6. **Final Answer**:
- The final answer is that there is no reaction, and the resulting solution remains clear and colorless.

### Summary of Options:
- **Option 1**: Colored ppt - Incorrect (no ppt forms)
- **Option 2**: Black ppt - Incorrect (no ppt forms)
- **Option 3**: Clear and colorless solution - Correct (no reaction occurs)
- **Option 4**: White ppt - Incorrect (no ppt forms)
