Solution:
Due to the acidic nature of the hydrogen atoms attached to a triple bonded carbon atoms, acetylene and terminal alkynes form metal acetylides. $ \underset{1-butyne}{\mathop{C{{H}_{3}}C{{H}_{2}}C\equiv CH}}\,+AgN{{O}_{3}}+N{{H}_{4}}OH $ $ \to \underset{silver\,butylide}{\mathop{C{{H}_{3}}C{{H}_{2}}C\equiv CAg}}\,+N{{H}_{4}}N{{O}_{3}}+{{H}_{2}}O $
