45. To determine acetic acid in acetonitrile, a coulometric titration method was used using OH ions formed during the electrolysis of water in the cathode space. The equivalence point was established potentiometrically. What is the molarity of CH3COOH if the current was 25.0 mA, the electrolysis time was t, and the volumes of the solutions studied V were as follows:
Options
t, s 107
V, ml 40.0
