FIRST-AID MEASURES ... Melting point/freezing point Not Available Initial boiling point and boiling range Not Available Flash point Not Flammable Evaporation rate Not Available 12.3.
Nitric Acid (approx. Mg+2HNO3---Mg(No3)2+H2. its melting point is -43 ºC and its boiling point is 83 ºC but its decomposition is accentuated at that temperature. Local minima occur at 32, 71, and 91 wt % acid. Chemsrc provides nitric acid(CAS#:7697-37-2) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. …63.19%, Nitric Acid 36.81% Boiling Point: Approximately 100°C Density: 1.22 Melting Point: Approximately 0°C Color: Colorless to light yellow liquid Physical State: Liquid pH Range: Solubility Information: Miscible Shelf Life: 24 Months Storage: Ambient DOT: UN2031, NITRIC ACID,… Nitric acid is corrosive to skin. Pure Nitric Acid is a colorless and odorless, viscous liquid, it decomposes slowly by the action of light, assuming a yellow coloration due to the NO 2 produced in the reaction. Melting point of nitric acid is -42 0 C and its boiling point is 86 0 C. Chemical Properties of nitric acid (HNO3) Rhenium (Re) Rhenium is a silver-white metal with the second highest melting point (3180 °C) after tungsten and has the highest boiling point. Vapor pressure at 20 °C: 9.4 torr OSHA PEL: 2 ppm Melting point: – 42 °C ACGIH TLV: 2 ppm Boiling point: 122 °C STEL: 4 ppm Hazardous Characteristics The freezing point curve for aqueous solutions of nitric acid has two maxima corresponding to melting points for the two hydrates of nitric acid: the monohydrate (77.77 wt% acid) at -37.62 °C and the trihydrate (58.83 wt% acid) at -18.47 °C.
Benzoic acid occurs naturally free and bound as benzoic acid esters in many plant and animal species. Nitric Acid, 70% w/w (7697 -37 -2) Persistence and degradability Biodegradability: not applicable.
