Which is manufactured by electrolysis of fused sodium chloride?

Options

A. `NaOH `
B. `NaCIO `
C. `NaClO_3`
D. `Na`.

Explanation

To determine which substance is manufactured by the electrolysis of fused sodium chloride, we can follow these steps:

### Step 1: Understand the Process of Electrolysis
Electrolysis involves the decomposition of a compound by passing an electric current through it. In this case, we are considering fused sodium chloride (NaCl).

### Step 2: Identify the Components of Fused Sodium Chloride
Fused sodium chloride consists of sodium ions (Na⁺) and chloride ions (Cl⁻). When electrolysis is performed, these ions will migrate towards the electrodes.

### Step 3: Determine the Reactions at the Electrodes
- **At the Cathode**: Sodium ions (Na⁺) are reduced to form sodium metal (Na).
\[ \text{Na}^+ + e^- \rightarrow \text{Na} \]

- **At the Anode**: Chloride ions (Cl⁻) are oxidized to form chlorine gas (Cl₂).
\[ 2\text{Cl}^- \rightarrow \text{Cl}_2 + 2e^- \]

### Step 4: Identify the Products of Electrolysis
From the above reactions, we can see that the products of the electrolysis of fused sodium chloride are sodium metal (Na) and chlorine gas (Cl₂).

### Step 5: Analyze the Given Options
The options provided are:
- NaOH
- NaClO
- NaClO₃
- Na

From our analysis, we can conclude that sodium metal (Na) is produced during the electrolysis of fused sodium chloride.

### Final Answer
The substance manufactured by the electrolysis of fused sodium chloride is **Na (sodium metal)**.
