Deacon's process is used for the manufacture of

Options

A. `HNO_(3)`
B. `I_(2)`
C. `Cl_(2)`
D. `Br_(2)`

Answer

**Step-by-Step Solution:**

1. **Understanding Deacon's Process**:
Deacon's process is a chemical reaction used to produce chlorine gas (Cl2) from hydrochloric acid (HCl) and oxygen (O2).

2. **Chemical Reaction**:
The reaction can be represented as:
\[ 4 \, \text{HCl} + \text{O}_2 \xrightarrow{\text{CuCl}_2} 2 \, \text{Cl}_2 + 2 \, \text{H}_2\text{O} \]
Here, copper(II) chloride (CuCl2) acts as a catalyst.

3. **Conditions of the Reaction**:
The reaction typically occurs at a temperature range of 400 to 450 degrees Celsius.

4. **End Product**:
The main product of Deacon's process is chlorine gas (Cl2). This chlorine gas is then used in various industrial applications, most notably in the production of bleaching powder (calcium hypochlorite).

5. **Commercial Importance**:
Bleaching powder is a valuable chemical used in water treatment, bleaching textiles, and as a disinfectant.

**Final Answer**: Deacon's process is used for the manufacture of chlorine gas (Cl2).
