Useful:

• Physical Properties: The nonahydrate is a yellowish-white crystalline solid; tetragonal crystals; odor of hydrogen sulfide; the color changes on exposure to light and air, first turning to yellow and then becoming brownish-black, deliquescent; density 1.43 g/cm3; decomposes at about 50°C; very soluble in water; aqueous solution strongly alkaline; slightly soluble in alcohol; insoluble in ether.
• Uses: Sodium sulfide is used in making sulfur dyes; for dehairing of hides; removing sulfur from viscous rayon; engraving and lithography; cotton printing; manufacturing rubber; paper pulp; and as a photographic reagent. Other major applications are for treating paper and for extracting gold ores where oxidized metal ores are converted to sulfides prior to froth flotation. Sodium sulfide also is used in preparing many other sulfides and as an analytical reagent. sodium sulphide nonahydrate has the following uses:sulfur dyestuff; leather depilatory;rayon denitration;dyeing auxiliary;sodium sulphide;including crystallization water; sodium sulphide or sulfureT;dyeing auxiliary. It is the precursor material for preparation of cadmium sulfide quantum dots. Also employed in the pulp and paper industry. It is likewise employed in the making of colors and dyestuffs. It is too useful in the trace quantities for the rapid synthesis of small silver nanocubes through mediating polyol reduction. It has as a significant role in breaking up the feather keratin useful for the preparation of bio-polymer. Sodium sulfide nonahydrate has been used as a source of H2S, to study the effect of H2S on amyloid fibrils associated with neurodegenerative diseases. It has been used in the preparation of sulfide standards for the quantitative analysis of sulfides in raw wastewater (sewage) samples.It serves as a catalyst during synthesis of thioamides.
