A new volumetric determination of pyrophosphate, based on the complex formation, has been carried out. The method was found to be superior to others, and the determination was made within the permissible error in usual volumetric analysis without the use of empirical factor. Quantitative precipitation of zinc pyrophosphate was formed in the pH range 3.83.9, and the chemical reactions in this case have been also investigated potentiometrically. In order to proceed for rapid gravimetric determination of orthophosphate, a volumetric method followed by the application of versenate complex has been performed.
