Options

A. Blue
B. chocolate
C. raddish brown
D. Bluish white

Answer

To solve the question regarding the reaction between \( \text{Zn}^{2+} \) ions and \( [\text{Fe(CN)}_6]^{4-} \) ions, we can follow these steps:

### Step 1: Identify the Reactants
We have two reactants:
- Zinc ions: \( \text{Zn}^{2+} \)
- Ferrocyanide ions: \( [\text{Fe(CN)}_6]^{4-} \)

### Step 2: Write the Reaction Equation
When zinc ions react with ferrocyanide ions, they form a precipitate. The balanced chemical reaction can be written as:
\[ \text{Zn}^{2+} + 2[\text{Fe(CN)}_6]^{4-} \rightarrow \text{K}_2[\text{ZnFe(CN)}_6] \downarrow \]
Here, \( \text{K}_2[\text{ZnFe(CN)}_6] \) represents the precipitate formed.

### Step 3: Determine the Color of the Precipitate
The precipitate formed from this reaction is known as zinc ferrocyanide. It is characterized by its bluish-white color.

### Step 4: Conclusion
Thus, the final answer to the question is that the precipitate formed is bluish-white.

### Final Answer
The precipitate formed is bluish-white.
