I-sodium sulfide yikristalu enemibala ehlukileko enephunga elimbi. Ihlangana nama-asidi ukukhiqiza i-hydrogen sulfide. Isixazululo sayo samanzi sine-alkali eqinileko, kungakho yaziwa nangokuthi yi-alkali ene-sulfurated. Incibilikisa isibabule ukwakha i-sodium polysulfide. Imikhiqizo yamabubulo kanengi ivela njengeenqhema ezipinki, ezibomvu-onsundu, nofana eziphuzi-onsundu ngebanga lokusilaphazeka. Iyabola begodu inobuthi. Lokha nayivezwa emoyeni, i-oxidize lula yenze i-sodium thiosulfate. I-hygroscope ephezulu, ukuncibilika kwayo e-100g yamanzi yi-15.4g (ku-10°C) kanye ne-57.3g (ku-90°C). Incibilika kancani ku-ethanol begodu ayincibiliki ku-ether.

Iinsetjenziswa ezikhethiweko ezisezingeni eliphezulu, ukulawulwa kwekhwalithi okuqinileko kiyo yoke ikambiso yokukhiqiza, ukuqinisekisa ikhwalithi ezinzileko kiyo yoke iqoqo le-sodium sulfide.
