ʻO ka sodium sulfide, kahi hui inorganic i ʻike ʻia hoʻi he odorous alkali, odorous soda, yellow alkali, a i ʻole sulfide alkali, he pauka crystalline kala ʻole i kona ʻano maʻemaʻe. He hygroscopic kiʻekiʻe ia a maʻalahi hoʻi e hoʻoheheʻe ʻia i ka wai, e hua mai ana i kahi hopena wai e hōʻike ana i nā waiwai alkaline ikaika. Hiki i ka pili ʻana me ka ʻili a i ʻole ka lauoho ke hana i nā kuni, no laila kona inoa maʻamau "sulfide alkali." Ke hōʻike ʻia i ka ea, e hoʻoheheʻe mālie ka hopena wai o ka sodium sulfide e hana i ka sodium thiosulfate, sodium sulfite, sodium sulfate, a me ka sodium polysulfide. Ma waena o kēia mau mea, ua hana ʻia ka sodium thiosulfate ma kahi wikiwiki, e lilo ia i huahana oxidation mua. Loaʻa i ka sodium sulfide ka deliquescence a me ka carbonation i ka lewa, e alakaʻi ana i ka decomposition a me ka hoʻokuʻu mau ʻana o ke kinoea hydrogen sulfide. Loaʻa pinepine i ka sodium sulfide ʻoihana nā haumia, e hāʻawi ana i nā aka e like me ka poni, ʻulaʻula-ʻeleʻele, a i ʻole melemele-ʻeleʻele. Hiki ke ʻokoʻa ke kaumaha kikoʻī, ke kiko heheʻe, a me ke kiko paila o ka hui ma muli o ka mana o kēia mau haumia.

Loaʻa iā Sodium sulfide ka palapala hōʻoia ʻaoʻao ʻekolu o SGS, palapala hōʻoia papa ʻoihana, a ua hala i ka palapala hōʻoia ʻōnaehana maikaʻi honua ISO a me ka palapala hōʻoia REACH.
