(Beilstein and Blaese.) Sodium ajitimonate, NaSbOs. Sol. in much HjO, but soon becomes decomp. into NaoHaSboO^. + 3iH20, composition of NasHoSbgOy + 6H2O, according to Beilstein and Blaese. 1000 pts. HjO dissolve O'Sl pt. NaSb03 + SiHaO at 12-3°. 1000 pts. alcohol of 15-8 % dissolve 0-13 pt. NaSb03 + 3iH20 at 12-3°. 1000 pts. alcohol of 25-6 % dissolve O'O? pt. NaSb03 + 3iH20 at 12-3°. Somewhat more sol. when freshly precipi- tated. Absolutely insol. in glacial HC2H3O2. Presence of NaOH or Na salts diminish sol- ubility, while NH4OH or K salts increase it slightly.
