I-Sodium sulfide iyikristalu enemibala ehlukahlukene enephunga elibi. Isabela nama-asidi ukuze ikhiqize i-hydrogen sulfide. Isixazululo sayo samanzi si-alkaline kakhulu, ngakho-ke saziwa nangokuthi i-sulfurated alkali. Sincibilikisa isibabule ukuze sakhe i-sodium polysulfide. Imikhiqizo yezimboni ivame ukubonakala njengezigaxa ezipinki, ezibomvu ngokunsundu, noma eziphuzi ngokunsundu ngenxa yokungcola. Iyabola futhi inobuthi. Uma ivezwa emoyeni, i-oxidizes kalula ukuze yakhe i-sodium thiosulfate. Njengoba i-hygroscopic kakhulu, ukuncibilika kwayo ku-100g wamanzi kungu-15.4g (ku-10°C) kanye no-57.3g (ku-90°C). Incibilika kancane ku-ethanol futhi ayincibiliki ku-ether.

Izinto zokusetshenziswa ezisezingeni eliphezulu ezikhethiwe, ukulawulwa kwekhwalithi okuqinile kuyo yonke inqubo yokukhiqiza, ukuqinisekisa ikhwalithi ezinzile yeqoqo ngalinye le-sodium sulfide.
