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 for the equation \( \text{Ag}_2\text{CO}_3 + 2\text{HCl} \rightarrow 2\text{AgCl} + \text{CO}_2 + \text{H}_2\text{O} \), we can analyze the reactants and products step by step.

### Step 1: Identify the Reactants and Products
The reactants in this reaction are silver carbonate (\( \text{Ag}_2\text{CO}_3 \)) and hydrochloric acid (\( \text{HCl} \)). The products are silver chloride (\( \text{AgCl} \)), carbon dioxide (\( \text{CO}_2 \)), and water (\( \text{H}_2\text{O} \)).

### Step 2: Analyze the State of the Reactants and Products
- \( \text{Ag}_2\text{CO}_3 \) is indicated as a precipitate (solid) since it has a downward arrow.
- \( \text{HCl} \) is a strong acid and is typically in aqueous form.
- \( \text{AgCl} \) is also indicated as a precipitate (solid) with a downward arrow.
- \( \text{CO}_2 \) is a gas, indicated by the upward arrow.
- \( \text{H}_2\text{O} \) is in liquid form.

### Step 3: Determine the Type of Reaction
In this reaction, we start with a precipitate (\( \text{Ag}_2\text{CO}_3 \)) and produce another precipitate (\( \text{AgCl} \)), along with a gas (\( \text{CO}_2 \)) and water. The key point to note is that a precipitate is formed from the reactants and another precipitate is produced in the products.

### Conclusion
Since we have a reaction where one precipitate is exchanged for another precipitate, this reaction is classified as a **precipitate exchange reaction**.

### Final Answer
The reaction \( \text{Ag}_2\text{CO}_3 + 2\text{HCl} \rightarrow 2\text{AgCl} + \text{CO}_2 + \text{H}_2\text{O} \) is a **precipitate exchange reaction**.
