Formulated specifically to meet the stringent requirements of the American Chemical Society, this solution is refined to minimize particulate contamination and trace metal impurities, which are critical in sensitive analytical applications. By maintaining low particulate counts, this reagent grade acid ensures minimal background interference and prevents micro-contamination in delicate processes. This high level of purity safeguards both analytical accuracy and substrate integrity, making it indispensable for critical operations where precision is paramount.\u003c\/p\u003e\u003cp\u003eAs a premier industrial chemical distributor, Alliance Chemical provides this high-concentration nitric acid to meet the demanding needs of advanced manufacturing, chemical testing, and scientific research environments. Explore our full range of high-purity products in our \u003ca href=\"\/collections\/acids\"\u003eacids collection\u003c\/a\u003e. This product is critical for surface preparation, metal dissolution, and chemical synthesis where standard technical grade acids would introduce unwanted residues that compromise final outcomes. Our Nitric Acid 70% ACS Grade - Low Particle is carefully packaged and handled in specialized containers to maintain its pristine state from our warehouse to your facility. This chemical solution represents our commitment to providing consistent, high-specification products designed for demanding technical and industrial workflows.\u003c\/p\u003e\u003ch3\u003eWhy This Grade\u003c\/h3\u003e\u003cp\u003eThe choice of ACS Reagent Grade with a strict 70% concentration is critical for processes that cannot tolerate variation or impurities. In semiconductor manufacturing, metal finishing, and quantitative chemical analysis, even part-per-million levels of metallic impurities or microscopic particulates can cause catastrophic failures. Utilizing a lower-grade acid, such as technical or industrial grade, introduces unwanted trace contaminants like iron or chloride. These impurities can alter the rate of chemical reactions, degrade silicon wafers during etching, or corrupt baseline data in analytical spectrometers. Check our \u003ca href=\"\/pages\/industries\/electronics\"\u003eelectronics industry solutions\u003c\/a\u003e for more info.\u003c\/p\u003e\u003cp\u003eFurthermore, the precise 70% concentration provides the optimal thermodynamic and chemical activity required for controlled oxidative reactions and passivation. Utilizing a weaker concentration or an inconsistent blend can result in incomplete passivation, leaving stainless steel vulnerable to premature corrosion and structural failure. In laboratory settings, variance in concentration directly compromises the stoichiometry of syntheses, leading to low yields or failed batches. For operations that require absolute reliability, this low-particle ACS grade eliminates these operational failure modes, ensuring consistent and predictable performance in every application.\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.
