✦ Synopsis
Automatx acid-base trtratlons were carned out by generating pH grachents m a continuous-flow mamfold A programmable, computer-controlled pump was used to produce vanable, reproducible flow-rate patterns that were used to mcrease gradually the tltrant concentration m the flow system A colorlmetrlc mdlcator reagent allowed the spectrophotmetrx detectIon of the eqmvalence pomt Strong and weak acids, both alone and m mtiures, and two protons of the same acid were titrated wth a relative standard deviation of 18% The procedure was apphed to the analysis of various real samples
