Thallium may be quantitatively separated on the anode from an ammoniacal solution containing silver ion as a cathodic depolarizer. The mean of 41 determinations gives 116.4 as equivalent weight of the oxide, with a standard deviation of 0.35. Under certain conditions the deposit of silver on the cathode is a precise measure of the thallium.Thallium(III) may be precisely estimated by back-titrating the solution of thallium at pH 3.5 with thorium nitrate and excess EDTA. Thallium(I) may be measured by a spectrophotometric titration at 222 µ with standard EDTA. Thallium-(III) may be estimated absorptiometrically from measurements on the chloroform extracts of thallium dibenzyldithiocarbamate at 430 µ. Thallium(I) may be estimated with an accuracy within 0.3% by direct coulometric oxidation at the anode in an acid solution. EXPERIMENTSwere carried out to determine the best conditions for the electrogravimetric separation of thallium from solution and for its volumetric, absorptiometric, and coulometric estimation.

“…He claimed that it was difficult to deposit thallium oxide quantitatively on the anode because of its tendency to deposit simultaneously on the cathode. Peltier and Duval (12) showed that thallic oxide prepared at the anode retains water very tenaciously. There is an almost horizontal region between 156°and 283°C.…”

The literature dealing with the high-temperature behavior of inorganic sulfates has been critically reviewed. Free energy functions of reactants and products of the decomposition reactions were calculated and have been tabulated from 298°K up to as high a temperature as possible. Free energy functions, equilibrium constants of reactions, and partial pressures of gaseous components were tabulated. Auxiliary data on phase transitions, densities, and kinetics of chemical decomposition have also been included.
