 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.  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.  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)
