Sodium bisulfate Usage And Synthesis
  • DescriptionSodium bisulfate is the sodium salt of sulfuric acid. It can be used as an acidifying/buffering agent in pesticide formulations applied to growing crops, as cooling and retort water treatment agent to inhibit corrosion on exteriors of canned goods, and as a feed additive.  Sodium bisulfate is used as a disinfectant in the manufacture of foods and pickling compounds. It is used in the dye industry and in the textile industry during bleaching step. Sodium bisulfate is also used as an acid bath in the jewelry for pickling, which removes the surface fire scale and oxides from the metal, leaving it a bright silver color.

  • Chemical PropertiesAlso known as sodium acid sulfate, niter cake, sodium hydrogen sulfate, NaHS04, is colorless crystals or white fused lumps,whose aqueous solution is strongly acid.It is soluble in water and noncombustible. Derived as a byproduct in the manufacture of hydrochloric acid and nitric acid, it is purified by recrystallization. Used as a flux for decomposing minerals,substitute for sulfuric acid in dyeing,disinfectant, in the manufacture of sodium hydrosulfide,sodium sulfate,and soda slum,for liberating CO2 in carbonic acid baths,in thermophores, for carbonizing wool, in the manufacture of magnesia cements,paper,soap,perfumes, foods, industrial cleaners, metal pickling compounds, and as a lab reagent.
  • UsesFlux for decomposing minerals; substitute for sulfuric acid in dyeing; disinfectant; manufacture of sodium hydrosulfide, sodium sulfate, and soda alum; liberating CO 2 in carbonic acid baths, in thermophores; carbonizing wool; manufacture of magnesia cements, paper, soap, perfumes, foods, industrial cleaners, metal pickling compounds; lab reagent.
  • Usessodium bisulfate is an inorganic salt used as an anti-septic and a pH adjuster in cosmetic creams. Concentrated solutions can produce strong irritation.
  • General DescriptionBisulfate, aqueous solution is a white crystalline solid dissolved in water. Sodium bisulfate is corrosive to metals and tissue.
  • Air & Water ReactionsDissolves in water to give strongly acidic solutions.
  • Reactivity ProfileAcidic salts, such as various BISULFATES, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions. The combination of calcium hypochlorite, sodium hydrogen sulfate, starch, and sodium carbonate, when compressed, caused the materials to incandescence, followed by explosion, [Ind. Eng. Chem., 1937, 15, 282].
  • HazardStrong irritant to tissue.
  • Health HazardTOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
  • Fire HazardNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
  • Safety ProfileA corrosive irritant to skin, eyes, and mucous membranes. Mutation data reported. Reacts with moisture to form sulfuric acid. Uxtures with calcium hypochlorite + starch + sodium carbonate explode when compressed. Violent reaction with acetic anhydride + ethanol may lead to ignition and a vapor explosion. Incompatible with calcium hypochlorite. When heated to decomposition it emits toxic fumes of SO, and NanO. See also SULFATES.
