Sodium sulfide ke kristale e mebala e fapaneng e nang le monko o nyonyehang. E arabela le li-acid ho hlahisa hydrogen sulfide. Tharollo ea eona ea metsi e na le alkaline e matla, ka hona e boetse e tsejoa e le alkaline e nang le sulfure. E qhala sebabole ho etsa sodium polysulfide. Lihlahisoa tsa indasteri hangata li hlaha e le maqhutsu a pinki, a bofubelu bo sootho, kapa a sootho bo bosehla ka lebaka la litšila. E senya ebile e chefo. Ha e pepesetsoa moeeng, e qhibiliha habonolo ho etsa sodium thiosulfate. E hygroscopic haholo, ho qhibiliha ha eona ka har'a 100g ea metsi ke 15.4g (ho 10°C) le 57.3g (ho 90°C). E qhibiliha hanyane ka har'a ethanol 'me ha e qhibilihe ka har'a ether.

Lisebelisoa tse tala tse khethiloeng tsa boleng bo holimo, taolo e tiileng ea boleng nakong eohle ea tlhahiso, ho netefatsa boleng bo tsitsitseng bakeng sa sehlopha se seng le se seng sa sodium sulfide.
