Various salts of phosphoric acid, such as monocalcium phosphate, are used as leavening agents.Phosphoric acid in soft drinks has the potential to cause dental erosion.<\/li>\n<li>Phosphoric acid also has the potential to contribute to the formation of kidney stones, especially in those who have had kidney stones previously.<\/li>\n<li>Rust removal\uff1aPhosphoric acid may be used to remove rust by direct application to rusted iron, steel tools, or other surfaces.<\/li><li>\nThe phosphoric acid changes the reddish-brown iron(III) oxide, Fe2O3 (rust), to ferric phosphate, FePO4.<\/li><li>\nLiquid phosphoric acid may be used for dipping, but phosphoric acid for rust removal is more often formulated as a gel.<\/li><li>\nAs a thick gel, it may be applied to sloping, vertical, or even overhead surfaces.<\/li><li>\nDifferent phosphoric acid gel formulations are sold as \"rust removers,\" \"rust killers\" or \"naval jelly.\" Multiple applications of phosphoric acid may be required to convert all rust.<\/li><li>\nRust may also be removed by phosphate conversion coating.<\/li><li>\nThis process can leave a black phosphate coating that provides moderate corrosion resistance.<\/li><li>\nMedicine\uff1aPhosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed.<\/li><li>\nPhosphoric acid is also an ingredient in over-the-counter anti-nausea medications that also contain high levels of sugar (glucose and fructose).<\/li><li>\nThis acid is also used in many teeth whiteners to eliminate plaque that may be on the teeth before application.<\/li>\n<\/ul>\n<h4 role=\"heading\" aria-level=\"2\">Other applications<\/h4>\n<ul>\n<li>As a solution for anodizing.<\/li>\n<li>As an external standard for phosphorus-31 nuclear magnetic resonance (31P NMR).<\/li>\n<li>As a buffer agent in biology and chemistry.
