a) A gaseous mixutre consists ethane and ehylene. How are the individual members recovered?
A gaseous mixture consists of ethylene and acetylene. How both are separated from each other?

Text Solution

Verified by Experts

Pass mixture through conc. `H_(2)SO_(4)`. Ethylene is absorbed. The product on heating gives again `C_(2)H_(4)`
b) Pass mixture through ammonial cuprous chlroide solution. The acetylene forms red precipitate. It is filtered and treated with `HNO_(3)` to recover accetylene.
`Cu_(2)C_(2)` (red ppt) `+2HNO_(3) to C_(2)H_(2) + Cu_(2)(NO_(3))_(2)`
