Anion radium and barium complexes STARaA!/sup 2-/ with Trilon B are formed at pH 5.5 to 6.9 as determined by using the tracers Ba/sup 149/ and Ra/sup 226/ and noting their distributions between a Cation exchanger and a solution with and without the complexing agent. The composition of the complex barium anion STABaA!/sup 2-/, as establisbed by Schwartzenbach, was confirmed. The formation of Ra and Ba complexes begins at a pH of about 4.5, while at a pH 78, no significant amounts of free Ba or Ra ions can be detected. The instabllity constant for the Ba complex was found to be pH = 7.69, which agrees with Schwartzenbach value of pH = 7.76 (potentiometric method) and with that of Schemid and Reilery of pK = 7.90 (polarographic method). The Ba complex (pK =7.69) was found to be somewhat stronger than the corresponding Ra complex (pH = 7.121. 18 references. (R.V.J.)
