100. Solving a chemistry problem

8. Acetic acid in acetonitrile was titrated with OH- ions formed from water during electrolysis in the cathode space. The equivalence point was set potentiometrically. What is the molarity of CH3COOH, if the current strength was 25.0 mA, and the electrolysis time was τ (s) and the volumes of the studied solutions V (ml) were as follows:
Option 8 9 10 11
τ , s 107 92 85 75
V, ml 40.0 50.0 60.0 80.0
SOLUTION FOR OPTION 8.
