Formulated as a clear, odorless, and colorless liquid, this aqueous solution provides a reliable source of orthophosphoric acid for diverse chemical applications. As a Texas-based industrial distributor, Alliance Chemical supplies this product to meet the rigorous specifications required for technical, manufacturing, and agricultural processes. The 75% concentration balance ensures manageable viscosity and high chemical activity, making it a preferred choice over weaker solutions for demanding pH adjustment and metal treatment operations.\u003c\/p\u003e\u003cp\u003eOur Phosphoric Acid 75% is designed for professional operators who require precise chemical performance. Characterized by its high density and low vapor pressure, this chemical offers excellent thermal stability and remains fully miscible in water. We recommend referencing the safety protocols outlined in the documentation before handling this strong acid. Alliance Chemical maintains strict quality control measures to ensure that each batch is consistent, reliable, and delivered safely to your facility. We provide a comprehensive Safety Data Sheet (SDS) provided with every order to support your facility’s hazard communication program.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eChoosing the 75% concentration of phosphoric acid is critical for processes that demand specific chemical kinetics without the excessive crystallization risks associated with higher concentrations like 85%. This concentration offers an optimal balance of orthophosphoric acid activity and fluid mechanics, ensuring smooth flow rates through industrial dosing pumps and piping networks. Utilizing a lower concentration would require transporting excess water, increasing logistics costs and diluting reactive mixtures beyond functional limits. Selecting the exact 75% concentration ensures your chemical reactions proceed at calculated rates without unnecessary dilution variables.\u003c\/p\u003e\u003cp\u003eUsing an incorrect grade or concentration of phosphoric acid can lead to severe operational failures. If a higher concentration is used, crystallization may occur in cooler climates, leading to clogged lines and damaged transfer equipment. Conversely, using a weaker or less controlled grade can introduce trace impurities that interfere with chemical synthesis, metal finishing, or catalyst preparation. In critical industrial manufacturing, these impurities can cause surface staining or compromise the integrity of rust conversion coatings. Alliance Chemical ensures that our 75% concentration remains within strict tolerances to eliminate these risks, and a Certificate of Analysis (COA) is available upon request to verify composition.\u003c\/p\u003e\n\u003cdiv class=\"chemical-profile\" data-source=\"canonical\"\u003e\n\u003ch3\u003eChemical Profile\u003c\/h3\u003e\n\u003cdl\u003e\n\u003cdt\u003eCAS Number\u003c\/dt\u003e\n\u003cdd\u003e7664-38-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eH3O4P\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e97.995 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003egreater than 266 °F at 760 mmHg (USCG, 1999)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e108 °F (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eFlash Point\u003c\/dt\u003e\n\u003cdd\u003e210 °C\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.892 at 77 °F (USCG, 1999) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003ePhosphoric acid appears as a clear colorless liquid or transparent crystalline solid.
