It is colourless column crystal, odorless, slightly deliquescence. The relative density is 2.04 and melting point is 60ºC. It is easily soluble in water but insoluble in ethahol. If heated below 100ºC, it can dissolve in crystal water and convert to monohydrate salt. When heated to 100ºC, it will lose crystal water and change its anhydrous substances, which will become sodium metaphosphate if it's continue to be heated.
