Kunwa mvura kwenguva refu ine sulfide yakawanda kunogona kukonzera kusanzwa kuravira zvakanaka, kurasikirwa nechido chekudya, kudzikira kwehuremu, kusakura zvakanaka kwebvudzi, uye muzviitiko zvakakomba, kuneta nerufu.

Hunhu hweNjodzi yeSodium sulfide: Chinhu ichi chinogona kuputika kana charova kana kupisa nekukurumidza. Chinoora kana paine acid, zvichiburitsa magasi ane chepfu uye anopisa.
Sodium sulfide Kupisa (Kuora) Zvigadzirwa: Hydrogen sulfide (H₂S), sulfur oxides (SOₓ).

Sodium sulfide inobvisa inki zvinobudirira muindasitiri yemapepa, iine ruzivo rwemakore makumi maviri mukutumira kunze kwenyika. Dzvanya kuti uwane rutsigiro rwechikwata chehunyanzvi.
