Sodium sulfide ikristaro ine ruvara rwakasiyana-siyana ine hwema hunosemesa. Inosangana nemaacids kugadzira hydrogen sulfide. Mvura yayo ine alkaline yakawanda, saka inozivikanwawo sesulfurated alkali. Inonyungudutsa sarufa kuti igadzire sodium polysulfide. Zvigadzirwa zvemaindasitiri zvinowanzoonekwa semapundu epingi, matsvuku-brown, kana yero-brown nekuda kwetsvina. Inoparadza uye ine chepfu. Kana yaiswa mumhepo, inonyunguduka nyore nyore kuti igadzire sodium thiosulfate. Yakanyanya hygroscopic, kunyunguduka kwayo mu100g yemvura i15.4g (pa10°C) uye 57.3g (pa90°C). Inonyunguduka zvishoma muethanol uye hainyunguduke mu ether.

Zvinhu zvakagadziriswa zvemhando yepamusoro zvakasarudzwa, kudzora mhando zvakasimba mukati mekugadzirwa, zvichiita kuti pave nemhando yakagadzikana ye sodium sulfide yega yega.
