The suspension milk of lime is composed of:

Options

A. `Ca(OH)_(2)`
B. `CaO`
C. `CaCl_2`
D. `CaSO_4`

Answer

To solve the question regarding the composition of suspension milk of lime, we can follow these steps:

### Step 1: Understand the Components
The question asks about the composition of milk of lime, which is a suspension. We need to identify the chemical components involved.

### Step 2: Identify Quick Lime
Quick lime is known as calcium oxide (CaO). When quick lime is mixed with water, it undergoes a chemical reaction.

### Step 3: Reaction with Water
When calcium oxide (CaO) reacts with water (H₂O), it forms calcium hydroxide (Ca(OH)₂). This process can be represented by the following chemical equation:
\[ \text{CaO} + \text{H}_2\text{O} \rightarrow \text{Ca(OH)}_2 \]

### Step 4: Formation of Milk of Lime
The resulting calcium hydroxide (Ca(OH)₂) in water creates a suspension known as milk of lime. This is not a solution but a suspension because calcium hydroxide does not completely dissolve in water.

### Step 5: Conclusion
From the above steps, we can conclude that the suspension milk of lime is composed of calcium hydroxide (Ca(OH)₂).

### Final Answer
The suspension milk of lime is composed of **calcium hydroxide (Ca(OH)₂)**.
