I-sodium sulfide yikristalu lenembala logucugucukako leneliphunga lelinyanyisako. Ihlangana nema-esidi kute ikhicite i-hydrogen sulfide. Sisombululo sayo lesinemanti sine-alkaline lenemandla, kungako siphindze satiwe ngekutsi yi-alkali lenesulfure. Incibilikisa sibabule kwenta i-sodium polysulfide. Imikhicito yemafemu ivame kuvela njengeticucu letipinki, letibovu-nsundvu, noma letiphuti-nsundvu ngenca yekungcola. Kuyagcoba futsi kunebuthi. Uma ihlangene nemoya, ivele ibe ne-oksijini kute yakhe i-sodium thiosulfate. I-hygroscopic kakhulu, kuncibilika kwayo ku 100g wemanti ngu 15.4g (ku 10°C) kanye na 57.3g (ku 90°C). Incibilika kancane ku ethanol futsi ayincibiliki ku ether.

Tintfo letikhetsiwe letisezingeni lelisetulu letiluhlata, kulawula lizinga lokucinile kuyoyonkhe inchubo yekukhicita, kucinisekisa lizinga lelizinzile kuyoyonkhe i-batch ye sodium sulfide.
