چکیده

A PDP-II online computer method for the titration of mixtures or 3 strong and a weak acid is described. The method is based on multiparametric curve-fitting. One of the parameters found from the calculations is the dissociation constant of the weak acid, hence the method can be applied even when this constant is unknown. Accurate results (relative error * 1%) were obtained for weak acids with pli, values of 0.2-10. A complete titration and calculation takes about 20 min.

Procedure for the simultaneous determination of tartaric and citric acids and total carbonate by potentiometric titrimetry and its application to antacid analysis.

The application of a linear algebraic method to the potentiometric titration of a mixture of tartaric and citric acids and sodium carbonate and sodium hydrogen carbonate (previously treated with strong acid), permits the determination of the concentration of each individual acid and the total equivalent of carbonate in antacids. It is also possible to determine individual concentrations of sodi...
