Chemical 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 groundwater or soil or to accumulate in the food chain
  • 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 the 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.
  • 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. It is also used in the dairy industry to reduce bacterial counts in bedding and ammonia emissions, preventing environmental mastitis and calf respiratory stress.
  • 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.
  • 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.
