It is primarily used in pulp and paper industry. Uses of Sodium sulfide – Na 2 S. Used in water treatment as an oxygen scavenger agent and also used as a metal precipitant. Utilized in the production of elastic synthetic materials, sulfur colors and other substances. SODIUM SULFIDE is a white to yellow crystalline material, flammable. Aqueous solutions of Na 2 S are strongly alkaline. Seek medical attention right away if any of these SEVERE side effects occur while taking sodium sulfide topical: Severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue). Sodium Sulfide is a moderately water and acid soluble Sodium source for uses compatible with sulfates.Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Used in the kraft process in the paper and pulp industry; Used as an oxygen scavenger agent in water treatment; Used as a bleaching agent in the textile industry; Used as an unhairing agent in the liming process during leather processing; Safety Measures. Can explode on rapid heating or when shocked. Application Na 2 S is used for H 2 S therapy, to study its effect on the prevention of diabetes in animals. Sodium Sulfide CAS RN: 1313-82-2 Major Uses. Sodium Sulfide Uses. Sodium sulfide is strong alkaline in nature it causes skin burns. Used in photographic industry to protect developer solutions from oxidation in textile industry sa bleaching. Violent reaction with carbon, charcoal, diazonium salts, N,N-dichloromethylamine, strong oxidizers, water. Sodium sulfide can be used as nucleophile in Sandmeyer type reactions. Applies to sodium sulfide topical: gel. It is a strong reducing agent and reacts with oxidants. Aqueous solution of sodium sulfide can be refluxed with nitro carrying azo dyes dissolved in dioxane and ethanol to selectively reduce the nitro groups to amine; while other reducible groups, e.g. On contact with acids it liberates highly toxic and flammable hydrogen sulfide gas. azo group, remain intact. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Na 2 S is soluble in water, slightly soluble in alcohol and insoluble in ether. No COMMON side effects have been reported with sodium sulfide gel. Casarett and Doull's Toxicology 2nd ed . Sodium Sulfide is a yellow to red solid; readily soluble in water, slightly soluble in alcohol. Cubic crystals of sodium sulfide (Na 2 S) are extremely hygroscopic in nature and discolor on exposure to air. In prodn of heavy water for nuclear reactors . Sodium sulfide reduces1,3-dinitrobenzene derivatives to the 3-nitroanilines.
