Identify the unknown product (x) in the following reaction
Milk of lime `+Cl_(2)tox+CaCl_(2)+H_(2)O`

Options

A. `Ca(OC l)_(2)`
B. `Ca(OH)_(2)`
C. `CaO`
D. `CaCO_(3)`

Answer

To identify the unknown product (X) in the reaction of milk of lime with chlorine, we can follow these steps:

### Step 1: Understand the Reactants
- Milk of lime is a common name for slaked lime, which is chemically represented as calcium hydroxide (Ca(OH)₂).

### Step 2: Write the Reaction
- The reaction can be written as:
\[ \text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{X} + \text{CaCl}_2 + \text{H}_2\text{O} \]

### Step 3: Identify the Products
- When calcium hydroxide reacts with chlorine, one of the products formed is calcium hypochlorite (Ca(OCl)₂), along with calcium chloride (CaCl₂) and water (H₂O).

### Step 4: Balance the Reaction
- To balance the reaction, we need to ensure that the number of atoms of each element is the same on both sides. The balanced equation is:
\[ 2 \text{Ca(OH)}_2 + 2 \text{Cl}_2 \rightarrow 2 \text{Ca(OCl)}_2 + 2 \text{CaCl}_2 + 2 \text{H}_2\text{O} \]
- This indicates that for every 2 moles of calcium hydroxide and chlorine, we produce 2 moles of calcium hypochlorite, 2 moles of calcium chloride, and 2 moles of water.

### Step 5: Identify the Unknown Product (X)
- From the balanced reaction, we can see that the unknown product (X) is calcium hypochlorite (Ca(OCl)₂).

### Conclusion
- Therefore, the unknown product (X) in the reaction is calcium hypochlorite (Ca(OCl)₂).

### Final Answer
- The correct answer is **Calcium hypochlorite (Ca(OCl)₂)**.
