This specific concentration represents a standard technical dilution designed for operations that require precise chemical activity without the hazards of manual dilution from 67% or 70% concentrates. While an official compendial grade is not applicable here, maintaining a consistent 20% assay ensures that reactions proceed at predictable rates. In industries like electronics or precision metal finishing, a deviation of even a few percentage points can lead to incomplete oxide removal or, conversely, excessive substrate etching.\u003c\/p\u003e\u003cp\u003eUsing an incorrect concentration or an unverified grade can lead to severe failure modes. If a weaker concentration is accidentally substituted, surface passivation or scale removal might fail, leaving contaminants that ruin subsequent coating or plating steps. On the other hand, using a more concentrated acid can cause runaway exothermic reactions, generate toxic nitrogen dioxide fumes, or permanently damage expensive stainless steel equipment. Our standardized Nitric Acid 20% eliminates the variable risks associated with in-house dilution, such as localized overheating or contamination from low-quality process water, ensuring a reliable feed for your process lines.\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\u003e7697-37-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eHNO3\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e63.013 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003e181 °F at 760 mmHg (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e-44 °F (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.5 at 77 °F (NIOSH, 2024) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eNitric acid, other than red fuming appears as a pale yellow to reddish brown liquid with reddish brown vapors and a suffocating odor.

Our Nitric Acid 5% provides a precise concentration designed for operations where stronger solutions, such as 68% or 70% nitric acid, would cause excessive oxidation, rapid substrate degradation, or dangerous runaway thermal events. If a process engineer attempts to use an off-spec or over-concentrated acid, they risk destroying sensitive metal parts during pickling or etching, leading to costly manufacturing scrap and equipment downtime.

ACS Grade specifications are set by the American Chemical Society, ensuring that the concentration of trace impurities like heavy metals, sulfates, and chlorides remains below extremely low thresholds. When performing analytical testing or high-tech manufacturing, utilizing a lower-grade acid can introduce unwanted metal ions, which act as catalysts for unintended side reactions or ruin delicate substrates. For instance, in \u003ca href=\"\/pages\/industries\/electronics\"\u003esemiconductor wafer processing\u003c\/a\u003e, even part-per-million levels of contamination will cause component failure and disrupt manufacturing yields.\u003c\/p\u003e\u003cp\u003eThe 65% concentration is the standard bench reagent strength, optimized for stability and reactivity. Lower concentrations may lack the necessary thermodynamic power to drive oxidation reactions, while higher concentrations (such as fuming nitric acid) present severe safety risks and spontaneous decomposition challenges. Using an incorrect concentration or an industrial-grade alternative can lead to incomplete digestion of analytical samples, leading to skewed calibration curves and invalid test results.

This clear to pale yellow liquid—with the molecular formula HNO3 and CAS number 7697-37-2—acts as a powerful oxidizing agent that facilitates rapid chemical reactions, surface passivation, and precise compound synthesis. Industries rely on this specific concentration for its consistent thermodynamic properties and reliable reactivity.\u003c\/p\u003e\n\u003cp\u003eOur nitric acid is carefully packaged to maintain its purity and stability during transport and storage. As a critical reagent in various industrial settings, this product undergoes strict quality control measures to ensure that it meets the rigorous standards required for your operations. We understand that chemical consistency is vital for maintaining process efficiency and preventing unexpected reaction variations. Whether you are using it for metal etching, chemical synthesis, or complex industrial cleaning, this 55-gallon drum format provides the high volume necessary to support continuous production cycles while minimizing container swap-over frequency.\u003c\/p\u003e\n\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\n\u003cp\u003eNitric Acid ACS 69% is formulated to meet the analytical standards established by the American Chemical Society (ACS). This grade is critical for processes where trace metal contaminants could compromise the final product, such as in semiconductor processing, precision electroplating, or analytical laboratory reagent preparation. Standard industrial grades often contain parts-per-million impurities that can cause catalytic interference or unwanted side reactions. By utilizing an ACS grade product, operators ensure that critical chemical pathways remain clean and predictable, reducing the risk of batch failure or material degradation in sensitive equipment.\u003c\/p\u003e\n\u003cp\u003eChoosing the 69% concentration instead of lower concentrations is necessary for applications requiring specific thermodynamic kinetics or strong oxidizing potential. Lower concentrations may not sufficiently passivate stainless steel surfaces, leading to incomplete oxide barrier formation and subsequent localized corrosion or pitting. Conversely, using highly concentrated or fuming grades when 69% is specified can result in overly aggressive reactions, dangerous off-gassing, or premature degradation of handling equipment. Our 69% formulation strikes the ideal balance for optimal reaction rates, reliable passivation, and safe, predictable handling in industrial-scale processes.\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\u003e7697-37-2\u003c\/dd\u003e\n\u003cdt\u003eChemical Formula\u003c\/dt\u003e\n\u003cdd\u003eHNO3\u003c\/dd\u003e\n\u003cdt\u003eMolecular Weight\u003c\/dt\u003e\n\u003cdd\u003e63.013 g\/mol\u003c\/dd\u003e\n\u003cdt\u003eBoiling Point\u003c\/dt\u003e\n\u003cdd\u003e181 °F at 760 mmHg (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eMelting Point\u003c\/dt\u003e\n\u003cdd\u003e-44 °F (NIOSH, 2024)\u003c\/dd\u003e\n\u003cdt\u003eSpecific Gravity\u003c\/dt\u003e\n\u003cdd\u003e1.5 at 77 °F (NIOSH, 2024) - Denser than water; will sink\u003c\/dd\u003e\n\u003cdt\u003eAppearance\u003c\/dt\u003e\n\u003cdd\u003eNitric acid, other than red fuming appears as a pale yellow to reddish brown liquid with reddish brown vapors and a suffocating odor.
