`BaC_(2)O_(4)darr+2AcOH to Ba(AcO)_(2)+H_(2)C_(2)O_(4)`

Options

A. For precipitate formation reaction
B. For precipitate dissolution reaction
C. For precipitate exchange reaction
D. For no reaction

Answer

To analyze the given reaction and determine its type, we can follow these steps:

### Step 1: Identify the Reactants and Products
The given reaction is:
\[ \text{BaC}_2\text{O}_4 \downarrow + 2 \text{AcOH} \rightarrow \text{Ba(AcO)}_2 + \text{H}_2\text{C}_2\text{O}_4 \]

Here, the reactants are:
- Barium oxalate (BaC₂O₄), which is indicated by the downward arrow (↓) that signifies it is a precipitate.
- Acetic acid (AcOH).

The products are:
- Barium acetate (Ba(AcO)₂).
- Oxalic acid (H₂C₂O₄).

### Step 2: Analyze the Precipitate
Since BaC₂O₄ is a precipitate (as indicated by the downward arrow), we need to consider what happens to this precipitate during the reaction.

### Step 3: Determine the Type of Reaction
In the products, we see that BaC₂O₄ is not present anymore, and instead, we have Ba(AcO)₂ and H₂C₂O₄. The BaC₂O₄ has effectively dissolved into the solution as it reacts with acetic acid to form soluble products.

### Step 4: Classify the Reaction
Given that a precipitate (BaC₂O₄) is dissolving and being transformed into soluble products, we classify this reaction as a **precipitate dissolution reaction**.

### Conclusion
Thus, the type of reaction is a **precipitate dissolution reaction**.
