Abstract: A neutralization anal. method was described for the detn. of H2SO4, CH3CHOHCOOH (I), and some volatile acids in a mixt. in nonaq, media by applying a potentiometric indication of equiv. points. For the detn. of H2SO4 and I, iso-PrOH, and in the presence of volatile acids, acetone media were the best. For titration in both cases 0.1 N iso-PrO3 Na in iso-PrOH was applied. In concns. of 10-100 mg. the exactness of the detn. of H2SO4 and I is ±1% for H2SO4 in the presence of volatile acids is ±1%, and for the other acids ±2%.
