| | Sodium bisulfate Usage And Synthesis |
| Description | Sodium bisulfate is a white crystalline solid dissolved in water. It is corrosive to metals and tissue.
Sodium bisulfate is hygroscopic in that it attracts water. Sodium bisulfate dissociates completely in water into sodium (Na+), hydrogen (H+) and sulfate (SO4-2). As a mineral acid, sodium bisulfate is not expected to contaminate ground water or soil or to accumulate in the food chain (EPA 1993).
Sodium 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.
| | Uses | Sodium bisulfate, or dry acid, is an acid salt known as sodium hydrogen sulfate. It can be used in a lot of ways such as food additives and cleaning, but in swimming pools, it's often used to lower pH balance and total alkalinity when they get too high. Porous aluminium can be fabricated by anodizing the metal in sodium hydrogen sulphate.
Sodium bisulfate is used as a top dressing to poultry litter to control ammonia in poultry houses. It is widely used in the commercial poultry industry (Blake and Hess 2001). It is also used in the dairy industry to reduce bacterial counts in bedding and ammonia emissions, preventing environmental mastitis and calf respiratory stress (Sun, et al. 2008).
| | Production Methods | Historically sodium bisulfate is a by-product from the manufacture of nitric acid from sodium nitrate and sulfuric acid. The by-product is referred to as niter cake. Today there are two methods for producing sodium bisulfate. One involves mixing sodium hydroxide with sulfuric acid which will react to form sodium bisulfate and water as shown in the equation below. This method, produced by JOST Chemical® (Jost Chemical 2014), results in a sodium bisulfate monohydrate which is used as a laboratory reagent.
NaOH + H2SO4 → NaHSO4 + H2O
The petitioner states that they use another sodium bisulfate production method that involves reacting sodium chloride (salt) and sulfuric acid at elevated temperatures to produce sodium bisulfate and hydrogen chloride gas as shown in the equation below.
NaCl + H2SO4 → NaHSO4 + HCl
According to the petitioner, the liquid sodium bisulfate is then sprayed and cooled so that it forms solid beads. The hydrogen chloride gas produced is dissolved in water to produce hydrochloric acid, which may be sold as a by-product.

| | Chemical Properties | Also 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. | | Physical properties | Colorless crystals; triclinic structure; density 2.435g/cm3 at 13°C; melts above 315°C; decomposes on further heating; soluble in water, 28.6 g/100mL at 25°C; highly soluble in boiling water, 100g/100 mL at 100°C; aqueous solution strongly acidic, pH of 0.1 M solution 1.4; insoluble in liquid ammonia; decomposed by alcohol into sodium sulfate and sulfuric acid. | | Uses | sodium bisulfate is an inorganic salt used as an anti-septic and a pH adjuster in cosmetic creams. Concentrated solutions can produce strong irritation. | | Uses | Sodium Hydrogen Sulfate is used in production of Nickel Hydroxide Electrode material for Alkaline battery. | | Uses | Flux for decomposing minerals; substitute for

Sodium bisulfate is corrosive to metals and tissue. | | Air & Water Reactions | Dissolves in water to give strongly acidic solutions. | | Reactivity Profile | Acidic 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]. | | Hazard | Strong irritant to tissue. | | Health Hazard | TOXIC; 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 Hazard | Non-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 Profile | A 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. |
