Suspension of slaked lime in water is known as

Options

A. lime water
B. quick lime
C. milk of lime
D. aqueous solution of slaked lime

Explanation

To solve the question "Suspension of slaked lime in water is known as," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components**:
- Slaked lime is chemically known as calcium hydroxide (Ca(OH)₂).
- It is derived from quicklime (calcium oxide, CaO) when it reacts with water.

2. **Understand the Reaction**:
- The reaction can be represented as:
\[ \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 \]
- Here, calcium oxide (quicklime) reacts with water to form calcium hydroxide (slaked lime).

3. **Properties of Slaked Lime**:
- Calcium hydroxide is a white powder and is sparingly soluble in water, meaning it does not fully dissolve but can form a suspension when mixed with water.

4. **Formation of Suspension**:
- When slaked lime is added to water, it does not dissolve completely but forms a suspension, similar to how sand behaves in water. This suspension appears as a cloudy white mixture.

5. **Identify the Correct Term**:
- The suspension of slaked lime in water is commonly referred to as "milk of lime." This term is used to describe the milky appearance of the suspension.

6. **Conclusion**:
- Therefore, the correct answer to the question is "milk of lime."

### Final Answer:
The suspension of slaked lime in water is known as **milk of lime**.
