It is a clear, colorless, syrupy liquid used for preparing buffers and standards, sample digestion, etching, and analytical chemistry.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat ACS grade guarantees.\u003c\/strong\u003e ACS reagent phosphoric acid assays at 85.0% minimum and limits impurities such as chloride, nitrate, sulfate, volatile acids, iron, and heavy metals to low parts-per-million levels, with color no darker than 10 Hazen. Those limits make it suitable for analytical and buffer work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow concentrated it is.\u003c\/strong\u003e With a density of about 1.685 g\/mL, 85% phosphoric acid contains roughly 1,430 g of H3PO4 per liter, about 14.6 M (calculated). It is viscous, mixes completely with water, and boils near 158 °C.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA triprotic acid.\u003c\/strong\u003e Phosphoric acid releases three protons in steps, with pKa values of about 2.15, 7.20, and 12.32. That makes it the basis of phosphate buffers across a wide range, including the widely used pH 7 region of dihydrogen and hydrogen phosphate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFreezing behavior.\u003c\/strong\u003e Concentrated phosphoric acid can crystallize at cool temperatures, since the pure 85% solution has a melting point near 21 °C. If crystals form, warm it gently to room temperature and mix before use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLaboratory uses.\u003c\/strong\u003e Labs use 85% phosphoric acid to prepare phosphate buffers and HPLC mobile phases, acidify samples, digest and dissolve materials, catalyze reactions such as dehydrations, and as an etchant in semiconductor processing for silicon nitride at elevated temperature.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiluting safely.\u003c\/strong\u003e To prepare dilute phosphoric acid, add the concentrated acid slowly to water with stirring. Dilution releases heat, though less violently than with sulfuric acid. Because the 85% acid is viscous, rinse measuring glassware carefully to transfer the full volume.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo sizes.\u003c\/strong\u003e The 100 mL size (ZP0995-125) suits occasional buffer preparation and teaching labs, while the 1 pint size (ZP0995-16) supports labs that prepare buffers and mobile phases regularly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandling at a glance.\u003c\/strong\u003e Concentrated phosphoric acid causes severe skin burns and eye damage and is corrosive to metals. Wear chemical splash goggles and acid-resistant gloves, and add acid to water when diluting.
