    Nitric Acid 64.6% Lab Grade

     Nitric Acid 64.6% Laboratory / Technical Grade *Excellent for gold refining Nitric Acid 64.6% (41° Baumé) (HNO3) is a highly corrosive mineral acid widely used in various industrial application.  It is a clear to pale yellow in color and is a strong oxidizing agent known for its corrosive properties.  It is commonly used in chemical manufacturing, metal processing, and as a laboratory reagent. This 64.6% Acid is in the high concentration range its slightly less azeotropic than 67% Nitric Acid which means it fumes less because the water and acid are not at the maximum boiling point. They are extremely close but the slightly small amount of extra water. You can achieve the reaction you are looking for it will fume less and take a little bit more time.  Another note is that our sulfuric acid 93% can be used with nitric acid/water mixtures to help shift the azeotropic point to make highly concentrated fuming nitric acid. Nitric Acid plays a key role in refining gold, particularly in methods like aqua regia refining and in parting processes.   Urban mining and pcb board gold recovery commonly uses nitric acid to dissolve gold.  *Ships in Level 4 Fluorinated Polyethylene Bottles, 55g ships in HDPE blue drum.  Aqua Regia Gold Refining Process (Most Common Use)Aqua regia is a mixture of nitric acid (HNO₃) and hydrochloric acid (HCl) in a 1:3 ratio. This combination dissolves gold, which neither acid can do alone. Step-by-step Overview:Preparation of Aqua Regia: Mix 1 part nitric acid with 3 parts hydrochloric acid. Dissolution: Add impure gold to the aqua regia. Nitric acid oxidizes the gold to gold ions (Au³⁺). Hydrochloric acid provides chloride ions (Cl⁻) to form chloroauric acid (HAuCl₄), which is soluble. Filtration: Filter the solution to remove impurities and undissolved metals. Precipitation: Add a reducing agent like sodium metabisulfite (Na₂S₂O₅) to the solution. This causes pure gold to precipitate out of solution as fine particles. Washing & Melting: Wash the gold powder, dry it, and melt it to form pure gold bars or granules.   Chemical Formula: HNO3 Molecular Weight: 63.013 CAS Registry Number: 7697-37-2 Appearance Colorless to faint yellow Odor: Acrid Density > 1.4078@ 25 °C Boiling Point: 248 'F 67.2% HNO3 Solubility in water: Completely Soluble GHS Pictograms:   GHS Signal Word: Danger GHS Hazard Statements: H272, H314, H330 GHS Precautionary Statements P210, P220, P260, P264, P271, P280, P284, P301+P330+P331, P302+P361+P354, P304+P340, P305+P354+P338, P316, P320, P321, P363, P370+P378, P403+P233, P405, and P501 UN Identification Number: 2031 Proper Shipping Name: Nitric Acid Transport Hazard Class: 5.1, 8 Packing Group: II DOT Placard:  Nitric Acid 64% Lab/Tech Grade Safety Data Sheet (SDS)  Nitric Acid 64% Lab/Tech Grade Certificate of Analysis (COA)

Nitric Acid for Metal Refining & Industrial Use

BVV’s Nitric Acid collection is built for high-performance industrial applications where strength and reliability are non-negotiable. Our concentrated Nitric Acid is a staple for professionals in precious metal refining, utilized specifically for the preparation of Aqua Regia to dissolve and purify gold, as well as for the critical processing of silver.

Beyond refining, this powerful oxidizing agent is essential for high-precision metal etching, heavy-duty cleaning of industrial equipment, and various chemical manufacturing processes. We understand the needs of high-volume facilities, which is why we offer scalable inventory ranging from individual bottles and cases to bulk drums.

Based in the Midwest, BVV provides the specialized Hazmat logistics required to get these materials to your shop quickly and safely. Whether you are stripping metals or managing a large-scale refining operation, our Nitric Acid delivers the industrial-strength utility your facility demands.

What is the concentration of your Nitric Acid?

Our standard laboratory Nitric Acid is typically offered at a concentration of 67% to 70%. This is the common "concentrated" grade used for most analytical and industrial chemical reactions.

Can I use this Nitric Acid for gold refining?

Yes. High-purity Nitric Acid is a primary component used to create Aqua Regia (a mixture of Nitric and Hydrochloric acid), which is the industry standard for dissolving and refining gold and other precious metals.

Is this Nitric Acid Reagent Grade?

We offer Nitric Acid that meets ACS Reagent Grade standards, ensuring low trace-metal content and high consistency for sensitive laboratory analysis and high-end manufacturing.

What are the proper storage requirements for Nitric Acid?

Nitric Acid must be stored in a cool, dry, and well-ventilated area away from direct sunlight. It should be kept in a dedicated acid cabinet, specifically separated from organic solvents and flammable materials, as it is a powerful oxidizer.

Why does Nitric Acid sometimes turn yellow?

Over time, concentrated Nitric Acid can partially decompose into nitrogen dioxide (NO2), which gives the liquid a yellowish tint. This generally does not affect the performance of the acid for most industrial applications.

Do you offer bulk drum pricing for industrial facilities?

Yes. For high-volume industrial users, we provide Nitric Acid in bulk drum quantities. Please contact our sales team for tiered pricing and custom freight logistics.

What PPE is required when handling Nitric Acid?

Nitric Acid is highly corrosive. Always wear appropriate chemical-resistant gloves (such as Nitrile or Butyl), a lab coat, and a full-face shield or safety goggles. Always work in a well-ventilated area or under a fume hood.

Are SDS and COA documents available?

Yes. To ensure your facility remains compliant with safety regulations, Safety Data Sheets (SDS) and Certificates of Analysis (COA) are available for download on our product pages.
