Sulfide ya sodiyumu ni kristu ifite amabara atandukanye kandi ifite impumuro mbi. Ikorana na aside igatanga sulfide ya hydrogen. Umuti wayo w'amazi ni alkaline cyane, bityo izwi kandi nka alkaline ya sulfure. Ishongesha sulfure igakora sodium polysulfide. Ibicuruzwa by'inganda bikunze kugaragara nk'udusimba tw'umutuku, umutuku wijimye, cyangwa umuhondo wijimye bitewe n'imyanda. Irangiza kandi irangiza. Iyo ishyizwe mu kirere, ihita ikora oxidation igakora sodium thiosulfate. Ifite hygroscopic nyinshi, gushonga kwayo muri garama 100 z'amazi ni 15.4g (kuri 10°C) na 57.3g (kuri 90°C). Irashonga gato muri ethanol kandi ntishobora gushonga muri ether.

Ibikoresho fatizo byatoranijwe bifite ubuziranenge bwo hejuru, kugenzura ubuziranenge mu gihe cyose cyo kubitunganya, no kwemeza ubuziranenge buhamye kuri buri gice cya sodium sulfide.
