Application Na 2 S is used for H 2 S therapy, to study its effect on the prevention of diabetes in animals. 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). Aqueous solutions of Na 2 S are strongly alkaline. It is primarily used in pulp and paper industry. Sodium sulfide is strong alkaline in nature it causes skin burns. Cubic crystals of sodium sulfide (Na 2 S) are extremely hygroscopic in nature and discolor on exposure to air. No COMMON side effects have been reported with sodium sulfide gel. Sodium Sulfide is a yellow to red solid; readily soluble in water, slightly soluble in alcohol. Sodium sulfide reduces1,3-dinitrobenzene derivatives to the 3-nitroanilines. Utilized in the production of elastic synthetic materials, sulfur colors and other substances. 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. Sodium sulfide can be used as nucleophile in Sandmeyer type reactions. Sodium Sulfide CAS RN: 1313-82-2 Major Uses. In prodn of heavy water for nuclear reactors . Na 2 S is soluble in water, slightly soluble in alcohol and insoluble in ether. 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. 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. SODIUM SULFIDE is a white to yellow crystalline material, flammable. Uses of Sodium sulfide – Na 2 S. Used in water treatment as an oxygen scavenger agent and also used as a metal precipitant. Violent reaction with carbon, charcoal, diazonium salts, N,N-dichloromethylamine, strong oxidizers, water. Sodium Sulfide Uses. It is a strong reducing agent and reacts with oxidants. azo group, remain intact. Can explode on rapid heating or when shocked. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Used in photographic industry to protect developer solutions from oxidation in textile industry sa bleaching. Casarett and Doull's Toxicology 2nd ed . Applies to sodium sulfide topical: gel. On contact with acids it liberates highly toxic and flammable hydrogen sulfide gas.
