Suggest a method (a flow sheet) to separate a mixture of ethane, ethene and ethyne.

Explanation

To separate a mixture of ethane (C2H6), ethene (C2H4), and ethyne (C2H2), we can follow a systematic approach using chemical reactions and physical properties. Below is a step-by-step solution along with a flow sheet for the separation process.

### Step-by-Step Solution:

1. **Initial Mixture**: Start with a mixture containing ethane, ethene, and ethyne.

2. **Reaction with Ammonium Hydroxide and Copper(I) Chloride**:
- Pass the mixture through a solution of ammonium hydroxide (NH4OH) and copper(I) chloride (CuCl).
