Abstract
The use of different cells for pH measurements for the determination o f equilibrium constants of metal complexes is discussed in relation to the liquid junction potential connected with them. The effects of H-a q(+) and OHaq- on this quantity are also considered. The literature va lues for the conversion factor A, representing the difference in pH va lue based on the calibration with NBS buffers and that defined in term s of H+ concentration, are discussed.
