Nitric Acid 5%

Why Nitric Acid 5%

Nitric Acid 5% in Reagent grade provides a pre-diluted, tightly controlled chemical formulation ideal for analytical methods and precise pH reduction where introducing trace contaminants is strictly unacceptable. Soluble in water, alcohols, and most organic solvents, this specific concentration allows for rapid integration into mixed chemical matrices without complicated phase separation. By utilizing an accurate 5% concentration, chemical laboratories and industrial facilities eliminate the highly exothermic dilution processes required when starting from concentrated stock solutions. Sourced to meet strict Reagent grade specifications, this colorless, fuming liquid delivers reliable consistency for standardized titrations, atomic absorption spectroscopy preparations, and sensitive industrial surface treatments. The specific CAS 7697-37-2 formulation ensures precise molarity calculations, allowing technicians to maintain strict operational controls over their chemical environments.

Best Applications for This Grade

• Commonly applied in trace metal analysis and laboratory sample digestion procedures, where a dilute yet highly pure oxidizer is strictly required to dissolve solid samples into a liquid state without adding background interference to the analytical instrumentation.
• Commonly applied in specialized industrial wastewater treatment systems requiring targeted pH adjustment, specifically in scenarios where Reagent grade purity is necessary to prevent the introduction of unwanted heavy metals or complexing agents into the discharge stream.
• Commonly applied in mild metal passivation processes to dissolve free iron and sulfide inclusions from the surface of stainless steel components, promoting the formation of a protective chromium oxide layer without aggressively etching the underlying base metal.
• Commonly applied in the controlled removal of localized mineral scales, calcium deposits, and metallic oxides from sensitive industrial equipment, utilizing the 5% concentration to prevent corrosive degradation of underlying alloys and fluid handling seals.

When to Choose a Different Grade

• If the buyer requires a moderately stronger acidic solution for aggressive industrial descaling, bulk metal pickling, or general pH control where Reagent grade purity is not economically necessary, evaluate Nitric Acid 20% or Nitric Acid 25%.
• If the manufacturing process dictates a higher concentration for heavy metal etching, rapid oxidation reactions, or industrial nitrogenation processes, transition to Nitric Acid 40%.
• If laboratory protocols demand a concentrated analytical acid strictly meeting the American Chemical Society standards for complex wet chemistry and standardized digestions, select Nitric Acid 65% ACS Grade.
• If the laboratory is performing highly sensitive trace metal analysis, inductively coupled plasma mass spectrometry, or semiconductor manufacturing requiring the absolute minimum of trace elements, utilize Nitric Acid 70% ACS Grade - Low Particle.
