`NaBr+AgNO_(3) to AgBr darr+NaNO_(3)`

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 \( \text{NaBr} + \text{AgNO}_3 \rightarrow \text{AgBr} \downarrow + \text{NaNO}_3 \), we can follow these steps:

### Step 1: Identify the Reactants and Products
- The reactants in this reaction are sodium bromide (\( \text{NaBr} \)) and silver nitrate (\( \text{AgNO}_3 \)).
- The products formed are silver bromide (\( \text{AgBr} \)) and sodium nitrate (\( \text{NaNO}_3 \)).

### Step 2: Analyze the Formation of the Precipitate
- In this reaction, silver bromide (\( \text{AgBr} \)) is formed as a product.
- The downward arrow (\( \downarrow \)) indicates that \( \text{AgBr} \) is a precipitate, meaning it is an insoluble solid that forms when the two reactants are mixed.

### Step 3: Classify the Reaction
- Since a precipitate is formed from the reaction of two soluble reactants, this type of reaction is classified as a **precipitate formation reaction**.
- The formation of a solid from two aqueous solutions is a characteristic of precipitation reactions.

### Conclusion
Based on the analysis, the reaction \( \text{NaBr} + \text{AgNO}_3 \rightarrow \text{AgBr} \downarrow + \text{NaNO}_3 \) is a **precipitate formation reaction**.

### Final Answer
The answer is **Option 1: Precipitate formation reaction**.
