Identify the unknown product (X) in the folowing reaction
milk of lime `+ Cl_(2)rarr X + CaCl_(2) + H_(2)O`

Options

A. `Ca(Ocl)_(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 dilute aqueous solution of calcium hydroxide, which is represented by the chemical formula \( \text{Ca(OH)}_2 \). Chlorine gas is represented by \( \text{Cl}_2 \).

### Step 2: Write the Reaction
The reaction can be written as:
\[ \text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow X + \text{CaCl}_2 + \text{H}_2O \]

### Step 3: Identify the Products
When calcium hydroxide reacts with chlorine, one of the products formed is calcium oxychloride, which has the formula \( \text{Ca(OCl)}_2 \). This compound can be considered as the unknown product (X).

### Step 4: Write the Balanced Reaction
Now, we can rewrite the reaction with the identified product:
\[ \text{Ca(OH)}_2 + \text{Cl}_2 \rightarrow \text{Ca(OCl)}_2 + \text{CaCl}_2 + \text{H}_2O \]

### Step 5: Confirm the Products
In this reaction, we have:
- \( \text{X} = \text{Ca(OCl)}_2 \) (calcium oxychloride)
- \( \text{CaCl}_2 \) (calcium chloride)
- \( \text{H}_2O \) (water)

### Final Answer
The unknown product (X) is \( \text{Ca(OCl)}_2 \) (calcium oxychloride).
