Nitric Acid 65%ACS Grade

Product Overview

Nitric Acid 65% ACS Grade is a high-purity aqueous solution of hydrogen nitrate (HNO3), formulated specifically for critical laboratory and industrial applications. Historically known as Aqua Fortis due to its ability to dissolve silver and most metals, this strong mineral acid acts as a potent oxidizing agent. Our formulation meets stringent ACS Reagent Grade specifications, ensuring low trace metal content and consistent assay levels required for analytical chemistry.

This colorless to pale yellow liquid is essential for processes requiring precise chemical reactions, such as HPLC mobile phase preparation, metal passivation, and fertilizer synthesis. Alliance Chemical supplies Nitric Acid 65% in robust packaging ranging from laboratory bottles to industrial drums, ensuring safe transport and storage. The product is manufactured under controlled conditions to maintain stability and prevent decomposition, providing reliable performance for engineers, researchers, and purchasing agents.

• Chemical Synthesis: Essential precursor in the production of nitrates for fertilizers, dye intermediates, and organic compounds.
• pH Adjustment: utilized in industrial water treatment and chemical processing to lower pH levels efficiently.
• Gold Refining: Used in the separation of gold and silver (parting) within metallurgy and jewelry manufacturing.

Safety Precautions

Nitric Acid 65% is a Class 8 Corrosive liquid and a strong oxidizer. It can cause severe skin burns and eye damage upon contact. Always handle in a well-ventilated area with appropriate engineering controls. Personnel must wear chemical-resistant gloves (neoprene or PVC), safety goggles, and a face shield. Store in a cool, dry place away from combustible materials, reducing agents, and bases. In the event of a spill, neutralize carefully with soda ash or lime before disposal.
