What Is The Melting Point Of Sodium Sulfide Nonahydrate?

The melting point of sodium sulfide nonahydrate is 54.5°C. It is a white to yellow crystalline solid with the chemical formula Na2S·9H2O. The compound is soluble in water and has a strong odor of hydrogen sulfide. It is commonly used in the production of paper pulp, dyes, and pharmaceuticals. When heated, it decomposes and releases toxic fumes, so proper ventilation and safety precautions should be taken.
