B. `Ca(OH)_(2)`
C. `CaCO_(3)`
D. `CaSO_(4)`

Answer

**Step-by-Step Solution:**

1. **Identify Lime Water**: Lime water is commonly known as a solution used in various chemical applications. It is important to determine what it is composed of.

2. **Chemical Composition**: Lime water is an aqueous solution of calcium hydroxide. The chemical formula for calcium hydroxide is \( \text{Ca(OH)}_2 \).

3. **Solubility**: Calcium hydroxide is sparingly soluble in water. At room temperature, it dissolves to a limited extent, approximately 1.5 grams per liter of water.

4. **Physical Properties**: Lime water is characterized as a clear and colorless solution. It has an earthy smell and a bitter taste.

5. **Conclusion**: Therefore, lime water is indeed an aqueous solution of calcium hydroxide.

**Final Answer**: Lime water is an aqueous solution of calcium hydroxide.
