✦ Synopsis

Numerical values of the stability constants for several zinc-pyrophosphate complexes were determined at 25Β°C and 0.20 M ionic strength using a potentiometric titration method. Values of 7.36, 4.49, and 5.63 were found for log K,,,,, 1% &nm, and log K,,,,,,. These constants govern the formation of the ZnP,O,*complex, the ZnHPZO,l-complex, and the ZnOHPz0,3-complex, respectively.

The use of different cells for pH measurements for the determination of equilibrium constants of metal complexes is discussed in relation to the liquid junction potential connected with them. The effects of Hf and OH, on this quantity are also considered. The literature values for the conversion fac
