How does acetylene react with the following reagents? Give the corresponding equations and name the product formed in the reactions?
Ammonical `AgNO_(3) and Cu_(2)Cl_(2)`

Explanation

Action with ammonical `AgNO_(3)` solution: When acetylene gas is passed through ammonical `AgNO_(3)` solution, a white ppt. of silver acetylide is formed
`underset("Acetylene")(H-C-=C-H+2AgNO_(3))+2NH_(4)OH to underset("Silver acetylide")(AgC-=CAg downarrow +2NH_(4)NO_(3)+2H_(2)O)`
Action with ammonical `Cu_(2)Cl_(2)` solution: When acetylene gas is passed through amoonical `Cu_(2)Cl_(2)` solution, a red pp.t of curpous acetylide is formed
`underset("Acetylene")(H-C-=C-H)+H+Cu_(2)Cl_(2)+2NH_(4)OH to underset("Cuprous acetylide")(CuC-=C Cu downarrow+2NH_(4)Cl+2H_(2)O`
