“…Homogeneous methods have been applied, generally with the formation of dense, easily-filterable precipitates, and sharper separations from impurities, to the determination of lead as sulphate by hydrolysis of sulphamic acid; 459 to the determination of bismuth as phosphate by hydrolysis of metaphosphoric acid,4Go and to the precipitation of bismuth as basic formate and its separation from lead by hydrolysis of urea. 461 Copper has been precipitated as cuprous tetraphenylborate by reduction, under homogeneous conditions, with ascorbic acid.462 Selective precipitation of silver chloride, bromide, and iodide in crystalline form has been carried out by controlled volatilisation of ammonia.463 A precipitate of crystalline ferric oxide is obtained by hydrolysis of NN-di-(2-hydro~yethyl)glycine.~~ Metal oxinates have been precipitated from homogeneous solution by hydrolysing 8-acetoxyquinoline to generate the reagent in s i t ~c . 4 ~~ The method has been applied to the precipitation of a dense form of thorium oxinate; 466 for direct weighing the precipitate must be dried at a very closely controlled temperature.…”
