DESCRIPTION
85. Solving a chemistry problem
75. Acetic acid in acetonitrile was titrated coulometrically with the help of OH ions formed during the electrolysis of water in the cathode space. The equivalence point was set potentiometrically. Calculate the molar concentration of CH3COOH if, at a current strength of 25.0 mA, the electrolysis time was t s, and the volume of the studied solution was V ml.
Task Electrolysis time, t, s Volume of acetic acid solution, V, ml
