Sodium sulfide is a yellow to brick red crystalline mass or fused solid with an odor of rotten eggs, it is an Inorganic Chemicals. If exposed to moist air Sodium sulfide is liable to spontaneous heating and may cause ignition of nearby combustible material. Sodium sulfide absorbs moisture from the air. Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:
