Lime water is a _________

Options

A. mixture
B. element
C. compound
D. All the above

Explanation

**Step-by-Step Solution:**

1. **Understanding Lime Water**: The question asks what lime water is. Lime water is a solution that contains calcium hydroxide (Ca(OH)₂) dissolved in water.

2. **Identifying the Type of Solution**: Lime water is specifically described as a saturated solution. This means that it contains the maximum amount of calcium hydroxide that can be dissolved in water at a given temperature.

3. **Defining Mixture**: A mixture is formed when two or more substances are combined but not chemically bonded. In the case of lime water, it consists of calcium hydroxide (a solid) and water (a liquid), which are not chemically combined.

4. **Conclusion**: Since lime water is a saturated solution of calcium hydroxide in water, and it consists of two different substances (calcium hydroxide and water) that are not chemically bonded, we can conclude that lime water is a **mixture**.

**Final Answer**: Lime water is a **mixture**.
