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

Options

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

Answer

To determine the type of reaction for the equation \(2AgNO_3 + Na_2C_2O_4 \rightarrow Ag_2C_2O_4 \downarrow + 2NaNO_3\), we can follow these steps:

### Step 1: Identify the Reactants and Products
- The reactants are \(2AgNO_3\) (Silver Nitrate) and \(Na_2C_2O_4\) (Sodium Oxalate).
- The products are \(Ag_2C_2O_4\) (Silver Oxalate) and \(2NaNO_3\) (Sodium Nitrate).

### Step 2: Analyze the Formation of Precipitate
- In this reaction, \(Ag_2C_2O_4\) is formed as a product. The downward arrow (↓) indicates that \(Ag_2C_2O_4\) is a precipitate, meaning it is an insoluble solid formed from the reaction.

### Step 3: Classify the Reaction
- Since a precipitate is formed from the reaction of two soluble reactants, this is classified as a **precipitate formation reaction**.

### Step 4: Conclusion
- Therefore, the type of reaction is a **precipitate formation reaction**.

### Final Answer
- The answer is: **For precipitate formation reaction**.
