`2AgNO_(3)+Na_(2)C_(2)O_(4) to Ag_(2)C_(2)O_(4)darr+2NaNO_(3)`

Options

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

Answer

To solve the given reaction and identify its type, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in the reaction are:
- 2AgNO₃ (Silver Nitrate)
- Na₂C₂O₄ (Sodium Oxalate)

### Step 2: Write the Reaction
The reaction can be written as:
\[ 2AgNO₃ + Na₂C₂O₄ \rightarrow Ag₂C₂O₄ + 2NaNO₃ \]

### Step 3: Identify the Products
The products formed are:
- Ag₂C₂O₄ (Silver Oxalate)
- 2NaNO₃ (Sodium Nitrate)

### Step 4: Analyze the Formation of Precipitate
When silver nitrate reacts with sodium oxalate, silver oxalate (Ag₂C₂O₄) is formed, which is a white precipitate. This indicates that a solid product is formed from the reaction of two aqueous solutions.

### Step 5: Determine the Type of Reaction
Since a precipitate is formed from the reactants, this reaction is classified as a **precipitate formation reaction**.

### Conclusion
The correct classification of the reaction is:
- **Precipitate Formation Reaction**
