Titrations of NH4 ggTc04 with Sn(ll)S04 and reverse titrations of Sn(ll)S04 with NH4 "Tc04 were performed at a M concentration level in the presence of 0.1 M EHDP at pH 2.5, 7.0 and 12.0, respectively. The end points were determined potentiometrically using platinum and saturated calomel electrodes.
