Sodium sulfide ji kristalo ko ni hiɛ sui srɔtoi ni ŋmɔlɔ yɔɔ mli. Ekɛ acid feɔ ekome ni ekɛ hydrogen sulfide baa. E-nu mli nu lɛ mli edɔ waa, no hewɔ lɛ ale lɛ hu akɛ sulfurated alkali. Ekɛ sulfur shwieɔ shi ni ekɛfeɔ sodium polysulfide. Bei pii lɛ, nitsumɔhei nibii jeɔ kpo tamɔ ŋmɔlɔŋmɔlɔ, ŋmɔlɔŋmɔlɔ-ŋmɔlɔ, loo ŋmɔlɔŋmɔlɔ-ŋmɔlɔ yɛ muji ni yɔɔ mli lɛ hewɔ. Efiteɔ nii ni eyɛ awui. Kɛ́ ekɛ ehe wo kɔɔyɔɔ mli lɛ, ehaa okside lɛ feɔ sodium thiosulfate oya. Ehe wa waa, ni ekɛ nu 100g mli shwieɔ shi ji 15.4g (yɛ 10°C mli) kɛ 57.3g (yɛ 90°C mli). Ekɛ ethanol shwieɔ shi fioo, ni eshwieee ether mli.

Nibii ni hi jogbaŋŋ ni ahalaa, nibii ni hi jogbaŋŋ lɛ anɔkwɛmɔ ni mli wa yɛ nifeemɔ lɛ mli fɛɛ, ni akwɛɔ koni sodium sulfide lɛ mli nibii ni hi jogbaŋŋ lɛ ahi shi jogbaŋŋ.
