✦ Synopsis

standard sodium dihydrogen phosphate (NaH:POa) solutions. The Lambert-Beer law was applicable over the range o.ooqg-o.oqg g P as phosphate.

Results and discussion

Results obtained for fourteen samples are given in Table I. The temperature and the time of heating the melt obtained from sodium dihydrogen phosphate which gave the glass on quenching, are also recorded. The weight-average molecular weights obtained by the viscosity methodi are also @ven.

The amount of phosphorus present as ring phosphate in various samples of Graham's salt appears to be quite reasonablez. This method is an improvement over qther methods, e.g. the chromatographic method", which are less quantitative.
