Abstract: The detn. of acetylene (I) with AgNO₃ (II) with direct potentiometric titration of excess and complex bound II by HCl is described. In this method the reaction soln. must be so prepd. that the equiv. ratio of I and II is kept const. The equiv. ratio of I to II is 1:2, or 1 ml. 0.1N soln. of II corresponds to 1.302 mg. of I. Because this reaction is reversible, HNO₃ formed during the reaction must be removed by the addn. of AcONa to keep the pH 4-5. The reaction time must be at least 10 min.; if shorter, the results are low.
