I-Sodium sulfide yikristale enemibala eguquguqukayo enevumba elibi. Isabela kunye nee-asidi ukuvelisa i-hydrogen sulfide. Isisombululo sayo samanzi sine-alkaline enamandla, yiyo loo nto ikwaziwa ngokuba yi-sulfurated alkali. Inyibilikisa i-sulfur ukwenza i-sodium polysulfide. Iimveliso zoshishino zihlala zibonakala njengeziqwenga ezipinki, ezibomvu-mdaka, okanye ezimthubi-mdaka ngenxa yokungcola. Iyabola kwaye inetyhefu. Xa ivezwa emoyeni, inyibilika ngokulula ukwenza i-sodium thiosulfate. Inyibilika kakhulu, ukunyibilika kwayo kwi-100g yamanzi yi-15.4g (kwi-10°C) kunye ne-57.3g (kwi-90°C). Inyibilika kancinci kwi-ethanol kwaye ayinyibiliki kwi-ether.

Izinto ezikhethiweyo ezikumgangatho ophezulu, ulawulo olungqongqo lomgangatho kuyo yonke inkqubo yemveliso, ukuqinisekisa umgangatho ozinzileyo kwibhetshi nganye ye-sodium sulfide.
