`K_(3)[Fe(CN)_(6)]+FeCl_(3) to Fe[Fe(CN)_(6)]

Options

A. For coloured ppt./Black ppt
B. For coloured solution.
C. for clear/colourless solution
D. For white ppt.

Answer

To solve the reaction of \( K_3[Fe(CN)_6] + FeCl_3 \) to form \( Fe[Fe(CN)_6] \), we need to analyze the reaction step by step.

### Step 1: Identify the Reactants
The reactants in this reaction are:
- \( K_3[Fe(CN)_6] \), which is potassium hexacyanoferrate(II).
- \( FeCl_3 \), which is iron(III) chloride.

### Step 2: Understand the Reaction
When \( K_3[Fe(CN)_6] \) reacts with \( FeCl_3 \), it forms a complex compound \( Fe[Fe(CN)_6] \), which is known as ferric ferrocyanide or Prussian blue.

### Step 3: Determine the Color of the Product
- When \( K_3[Fe(CN)_6] \) reacts with \( FeCl_3 \), the product formed is a colored solution.
- Specifically, the reaction with \( FeCl_3 \) results in a brown-colored solution.

### Step 4: Conclusion
Since we are asked whether the result is a colored precipitate, a black precipitate, a colorless solution, or a white precipitate, we conclude that:
- The reaction with \( FeCl_3 \) leads to a brown color solution, not a precipitate.

Thus, the answer to the question is that the product is a **brown color solution**.

### Final Answer
The final answer is **B: Brown color solution**.
