`Pb(NO_(3))_(2)+H_(2)SO_(4) to PbSO_(4)darr+2HNO_(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 represented by the equation:

\[ \text{Pb(NO}_3\text{)}_2 + \text{H}_2\text{SO}_4 \rightarrow \text{PbSO}_4 \downarrow + 2 \text{HNO}_3 \]

we can analyze the components and the nature of the products formed in the reaction.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
- The reactants are lead(II) nitrate \(\text{Pb(NO}_3\text{)}_2\) and sulfuric acid \(\text{H}_2\text{SO}_4\).
- The products are lead(II) sulfate \(\text{PbSO}_4\) and nitric acid \(\text{HNO}_3\).

2. **Observe the Formation of Precipitate**:
- In this reaction, \(\text{PbSO}_4\) is formed as a product. The downward arrow (\(\downarrow\)) indicates that \(\text{PbSO}_4\) is a precipitate, meaning it is insoluble in water and will settle out of the solution.

3. **Classify the Reaction Type**:
- Since a solid precipitate \(\text{PbSO}_4\) is formed from the reactants, this reaction is classified as a **precipitate formation reaction**.

4. **Consider Other Reaction Types**:
- If the precipitate were to dissolve, it would indicate a precipitate dissolution reaction.
- If both reactants and products contained precipitates, it would indicate a precipitate exchange reaction.
- Since we only have the precipitate on the product side, we conclude it is a precipitate formation reaction.

5. **Final Answer**:
- The type of reaction is **precipitate formation reaction**.
