Potentiometric determination of sulfuric and formic acids in nonaqueous solution

F. Onuška

Chemko, Strážske

 

Abstract: To det. H2SO4 and HCO2H in the reaction product of pentaerythritol production, mix 4 ml. of the reaction product with 40 ml. of acetone and titrate potentiometrically with 0.1N Me4NOH in 7:1 C6H6-MeOH. Reference and indicator electrodes were satd. calomel and glass, resp. The 1st step on the titration curve corresponds to 1st neutralization of H2SO4, and the 2nd step to 2nd neutralization of H2SO4 and to neutralization of HCO2H. The accuracy is <1%.
