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.
