Sodium sulfide, hydrated, with not less than 30% water
Sodium sulfide, hydrated, with not less than 30% water appears as yellow-pink or white deliquescent crystals, flakes or lumps. Contains at least 30% water. Alkaline. Burns skin, eyes and mucous membranes. Mildly corrosive to most metals. May be toxic by skin absorption. Releases toxic hydrogen sulfide gas when mixed with an acid. — CAMEO Chemicals
