When `K_(2)MnO_(4)` is added in solution of `NH_(4)Cl` then

Options

A. Green colour will appear
B. Yellow colour will appear
C. Pink colour will appear
D. Colour will appear

Answer

To solve the question "When K₂MnO₄ is added to a solution of NH₄Cl, what color will appear?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this case are potassium manganate (K₂MnO₄) and ammonium chloride (NH₄Cl).

2. **Understand the Reaction**:
- When K₂MnO₄ is added to NH₄Cl, a chemical reaction occurs. The potassium manganate reacts with ammonium chloride to produce potassium permanganate (KMnO₄), manganese dioxide (MnO₂), potassium chloride (KCl), ammonia (NH₃), and water (H₂O).

3. **Write the Balanced Chemical Equation**:
- The balanced chemical equation for the reaction is:
\[ K_2MnO_4 + 4 NH_4Cl \rightarrow 2 KMnO_4 + 2 MnO_2 + 2 KCl + 4 NH_3 + 2 H_2O \]

4. **Identify the Colors of the Products**:
- Potassium permanganate (KMnO₄) is known to have a pink color.
- Manganese dioxide (MnO₂) is light brown.
- Potassium chloride (KCl) and ammonia (NH₃) are colorless.

5. **Determine the Resulting Color**:
- When the pink color of KMnO₄ combines with the light brown color of MnO₂, the resulting mixture will appear yellow.

6. **Conclusion**:
- Therefore, when K₂MnO₄ is added to a solution of NH₄Cl, the color that will appear is yellow.

### Final Answer:
The correct answer is that a **yellow color** will appear.
