`Ag_(2)CO_(3)darr+2HCl to AgCldarr+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 analyze the given chemical reaction and determine the type of reaction it represents, we will follow these steps:

### Step 1: Write down the given reaction
The reaction provided is:
\[ \text{Ag}_2\text{CO}_3 \, (s) + 2 \text{HCl} \, (aq) \rightarrow 2 \text{AgCl} \, (s) + \text{CO}_2 \, (g) + \text{H}_2\text{O} \, (l) \]

### Step 2: Identify the reactants and products
- **Reactants**: Silver carbonate (\( \text{Ag}_2\text{CO}_3 \)) and hydrochloric acid (\( \text{HCl} \))
- **Products**: Silver chloride (\( \text{AgCl} \)), carbon dioxide (\( \text{CO}_2 \)), and water (\( \text{H}_2\text{O} \))

### Step 3: Analyze the formation of precipitates
- **Precipitate Formation**: A precipitate is formed when two solutions react to produce an insoluble compound. In this case, \( \text{Ag}_2\text{CO}_3 \) is a solid precipitate, and \( \text{AgCl} \) is also a solid precipitate formed in the products.

### Step 4: Determine the type of reaction
- Since both the reactants and products involve precipitates, we need to classify the type of reaction:
- **Precipitate Formation Reaction**: This occurs when a precipitate forms from soluble reactants.
- **Precipitate Dissolution Reaction**: This occurs when a precipitate dissolves into soluble reactants.
- **Precipitate Exchange Reaction**: This occurs when there is a change in the type of precipitate formed.

In this case, we started with \( \text{Ag}_2\text{CO}_3 \) (a precipitate) and ended with \( \text{AgCl} \) (another precipitate). Therefore, we can conclude that this is a **precipitate exchange reaction** because the precipitate formed in the products is different from the one in the reactants.

### Step 5: Conclusion
Thus, the correct classification of the reaction is:
- **Precipitate Exchange Reaction**
