`BaCO_(3)darr+2AcOH to Ba(AcO)_(2)+CO_(2)uarr+H_(2)O`

Options

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

Answer

To determine the type of reaction represented by the equation:

\[ \text{BaCO}_3 (s) + 2 \text{AcOH} \rightarrow \text{Ba(AcO)}_2 (aq) + \text{CO}_2 (g) + \text{H}_2O (l) \]

we can follow these steps:

### Step 1: Identify the Reactants and Products
- **Reactants**: Barium carbonate (BaCO₃) and acetic acid (AcOH).
- **Products**: Barium acetate (Ba(AcO)₂), carbon dioxide (CO₂), and water (H₂O).

### Step 2: Analyze the State of Reactants and Products
- **BaCO₃** is indicated as a solid (s), which means it is a precipitate.
- **AcOH** is a liquid (not specified but typically assumed).
- **Ba(AcO)₂** is indicated as aqueous (aq), meaning it is soluble in water.
- **CO₂** is a gas (g), which will escape from the solution.
- **H₂O** is a liquid (l).

### Step 3: Determine the Type of Reaction
- Since BaCO₃ is a precipitate that is reacting with acetic acid to form soluble barium acetate, along with gaseous carbon dioxide and liquid water, we can conclude that BaCO₃ is dissolving in the reaction.
- The presence of a solid reactant that forms soluble products indicates a dissolution process.

### Conclusion
Based on the analysis, the reaction is classified as a **precipitate dissolution reaction** because a solid (BaCO₃) is dissolving to form soluble products (Ba(AcO)₂) and releasing gas (CO₂).

### Final Answer
The type of reaction is **precipitate dissolution reaction**.
