Correct Answer: Acidic Property
Solution : The correct option is Acidic Property.
Because of the existence of hydrogen atoms that may be ionised as protons (H+), acetylene (C2H2) shows acidic properties in its interactions with silver nitrate (AgNO3). The following reactions can occur when acetylene interacts with silver nitrate: C 2 H 2 + 2AgNO 3 + 2NH 3 → Ag-C≡C-Ag + 2NH 4 NO 3 . Acetylene (C2H2) combines with silver nitrate (AgNO3) and ammonia (NH3) to generate the white precipitate of silver acetylide (Ag-C≡C-Ag) in this reaction, while ammonium nitrate (NH4NO3) stays dissolved in the solution. Because hydrogen atoms in acetylene may ionise to generate protons (H+), the solution becomes acidic due to the presence of H+ ions. Because of this, acetylene is classified as an acidic chemical in its interactions with specific compounds such as silver nitrate.
