Lane's process is for the preparetion of

Options

A. `H_(2)`
B. `H_(2)O`
C. `H_(2)O_(2)`
D. `D_(2)O`

Answer

**Step-by-Step Solution:**

1. **Understanding Lane's Process**: Lane's process is primarily used for the preparation of dihydrogen (H₂). It involves two main stages: oxidation and reduction.

2. **Oxidation Stage**: In the first stage, steam (H₂O) is passed through iron filings at high temperatures (between 1023 K and 1073 K). The reaction can be represented as:
\[ \text{Fe} + \text{H}_2\text{O} \rightarrow \text{Fe}_3\text{O}_4 + \text{H}_2 \]
Here, dihydrogen (H₂) is produced as a product of the reaction.

3. **Reduction Stage**: In the second stage, the iron oxide (Fe₃O₄) formed in the first stage is reduced back to iron using water gas, which is a mixture of carbon monoxide (CO) and steam (H₂O). The reaction can be represented as:
\[ \text{Fe}_3\text{O}_4 + \text{CO} \rightarrow \text{Fe} + \text{CO}_2 \]
This process is also referred to as vivification.

4. **Conclusion**: Thus, Lane's process is specifically designed for the manufacturing of dihydrogen (H₂).

**Final Answer**: Lane's process is for the preparation of dihydrogen (H₂).
