When water is added to compound (A) of calcium, solution of compound (B) is formed. When carbon dioxide is passed into the solution, it turns milky due to the formation of compound (C). If excess of carbon dioxide is passed into the solution milkiness disappears due to the formation of compound (D). Identify the compounds A,B,C and D. Explain why the milkiness disppears in the last step.

To solve the problem, let's identify the compounds A, B, C, and D step by step, along with the reasoning behind each identification. ### Step 1: Identify Compound A When water is added to compound A, a solution of compound B is formed. Since we are dealing with calcium compounds, we can consider calcium oxide (CaO) as compound A. **Reaction:** \[ \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 \] ...
