Why Nitric Acid 20%

Nitric Acid 20% Technical Grade delivers a moderate, controlled concentration of HNO3, designed specifically to balance acidic strength with manageable reactivity for industrial manufacturing and environmental management. As a clear, colorless to slightly yellow liquid that is fully miscible with water and most organic solvents, this targeted 20% dilution allows wastewater operators and facility managers to precisely control pH levels without the severe fuming, intense vapor pressure, or rapid exothermic reactions characteristic of concentrated fuming nitric acid. By integrating a pre-diluted 20% solution directly into production lines, facilities eliminate the labor, localized heat generation, and inconsistent batching associated with on-site acid dilution. This technical grade formulation ensures reliable performance across heavy industrial sectors where strict analytical purity is unnecessary, but consistent chemical behavior and dependable acidity are mandatory.

Best Applications for This Grade

  • Industrial wastewater treatment: Commonly applied in heavy effluent neutralization processes, where a moderate, nitrate-yielding acid effectively reduces the pH of highly alkaline waste streams to meet environmental discharge targets.
  • Metal finishing and surface preparation: Functions as an effective pickling and descaling agent to strip localized oxidation, rust, and manufacturing scale from industrial metals, ensuring a clean substrate without aggressively dissolving the underlying base metal.
  • Environmental remediation operations: Commonly applied in complex soil washing and groundwater treatment systems to rapidly solubilize specific metal contaminants, facilitating their extraction and subsequent recovery from affected industrial sites.
  • Manufacturing pH control: Serves as a reliable, moderate-strength titrant in large-volume chemical processing, providing operators with tighter titration curves and preventing sudden over-acidification that frequently occurs when dosing higher-percentage acids.

When to Choose a Different Grade

  • If the facility processes require a slightly stronger industrial-grade acid to decrease metal pickling durations or to neutralize extremely high-alkalinity bulk streams, evaluate Nitric Acid 25% or Nitric Acid 40%.
  • If the manufacturing system dictates a much weaker acidic solution to perform highly sensitive, micro-dose pH adjustments that prevent target overshoot, choose Nitric Acid 5%.
  • If the application involves exacting trace metal analysis, sample digestion, or analytical laboratory methods requiring certified reagent purity levels, select Nitric Acid 65% ACS Grade.
  • If the process involves sensitive fabrication techniques or specialized instrumental analysis demanding strict limits on trace impurities and physical particulates, utilize Nitric Acid 70% ACS Grade - Low Particle.
