It will cause burns when it touches the skin and hair, so sodium sulfide is commonly known as alkali sulfide. When exposed to air, sodium sulfide releases toxic hydrogen sulfide gas with the smell of rotten eggs. The color of industrial sodium sulfide is pink, reddish brown, and khaki because of impurities. Has an odor. Soluble in cold water, easily soluble in hot water, slightly soluble in alcohol. Industrial products are generally mixtures of crystal water of different shapes, and contain different degrees of impurities. In addition to different appearance and color, density, melting point, boiling point, etc. are also different due to the influence of impurities.
