Acetylene is prepared by the electrolysis of concentrated aqueous solution of

Acetylene can be prepared by the electrolysis of a concentrated aqueous solution of calcium carbide (CaC2). Here are the steps:

1. First, you need to prepare a concentrated aqueous solution of calcium carbide. This can be done by dissolving calcium carbide in water.

2. Next, you need to set up your electrolysis apparatus. This typically involves two electrodes (an anode and a cathode) connected to a power source, and immersed in the solution.

3. Once the apparatus is set up, you can start the electrolysis process by turning on the power source. This will cause the calcium carbide to break down.

4. During electrolysis, acetylene gas (C2H2) is produced at the cathode.

5. The acetylene gas can then be collected and stored for future use.

Please note that this is a simplified explanation and actual laboratory procedures may vary. Always follow safety guidelines when conducting experiments.
