What happens when excess of `CO_2` is passed through lime water ?

Explanation

When excess CO2 is passed through lime water (which is a solution of calcium hydroxide, Ca(OH)2), a chemical reaction occurs. Here’s a step-by-step breakdown of the process:

### Step 1: Identify the Reactants
- The reactants in this reaction are lime water (Ca(OH)2) and carbon dioxide (CO2).

### Step 2: Write the Initial Reaction
- When CO2 is bubbled through lime water, it reacts with calcium hydroxide. The reaction can be represented as:
