QUANTITATIVE ANALYSIS OF VERY WEAK ACID AND BASE BY pH-FIXED TITRATION METHOD

Jiangsu Institute of Chemical Technology Changzhou 213016

Received Date: 6 December 1989

pH-fixed titration method for the determination of weak acids and bases has been studied in this paper.It is not necessary to know the ionization constant of weak acid or base and the concentration of titrant.This method had been applied to determine phenol, 4-aminoantipyrine and glycine, whose ionization constants range from 10^-10 to 10^-12.The results were satisfactory.
