| Pure sodium sulfide is a colorless crystalline powder. Strong moisture absorption, soluble in water. Reaction was strongly alkaline aqueous solution. Touched the skin and hair will cause burns. It is commonly known as sodium sulfide sodium sulfide. Aqueous solution of sodium sulfide in the air will be slowly oxidized to sodium thiosulfate, sodium sulfite, sodium sulfate and sodium sulfide. Sodium thiosulfate as a result of the generation of faster, so the main product of oxidation is sodium thiosulfate. Deliquescence sodium sulfide in the air, and carbonated twisted, constant release of hydrogen sulfide gas. Industrial sodium sulfide containing impurities because of their color was pink, brown-red, yellow soil. Weight, melting point, boiling point, due to the effects of different impurities. |
