Solubility data for the Na O-P20 -H ° system have been reported in 13 differentpublications (1-13). Some of tflese (i-71 report the solubility fn systems in which
there is a range of Na/P ratios. Others (8-13) are limited to one Na/P ratio, i.e.,
the solubility of a given sodium phosphate in water is reported.
Many solid phases have been reported or suggested as being in equilibrium with
saturated solutions in the Na20-P2
-H20 system. These ...
