What will happen if to a solution of `Ca(HCO_(3))_(2)` formed by passing the carbon dioxide through a milky solution of `CaCO_(3)` for a longer time, ammonia solution is added?

Explanation

To solve the question regarding what happens when ammonia solution is added to a solution of calcium hydrogen carbonate (Ca(HCO₃)₂), which is formed by passing carbon dioxide through a milky solution of calcium carbonate (CaCO₃) for a longer time, we can follow these steps:

### Step-by-Step Solution:

1. **Formation of Calcium Hydrogen Carbonate**:
- When carbon dioxide (CO₂) is passed through a milky solution of calcium carbonate (CaCO₃), it reacts with water (H₂O) and calcium hydroxide (Ca(OH)₂) to form calcium hydrogen carbonate (Ca(HCO₃)₂).
- The reaction can be represented as:
\[
