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.
