It is one of severalsodium phosphates. Thesaltis known inanhydrousform as well ashydratesNa2HPO4·nH2O, wherenis 2, 7, 8, and 12. All are water-soluble white powders. The anhydrous salt ishygroscopic. ThepHof disodium hydrogen phosphate water solution is between 8.0 and 11.0, meaning it is moderatelybasic:
