Nitric acid is a corrosive acid and a powerful oxidizing agent. The major hazard posed by it is chemical burns, as it carries out acid hydrolysis with proteins and fats , which consequently decomposes living tissue (e.g. skin and flesh). Concentrated nitric acid stains human skin yellow due to its reaction with the keratin.
Aqua regia (/ ˈ r eɪ ɡ i ə, ˈ r iː dʒ i ə /; from Latin, "regal water" or "royal water") is a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3. [ b ] Aqua regia is a fuming liquid.
Commonly used mineral acids are sulfuric acid (H 2 SO 4), hydrochloric acid (HCl) and nitric acid (HNO 3); these are also known as bench acids. [1] Mineral acids range from superacids (such as perchloric acid) to very weak ones (such as boric acid). Mineral acids tend to be very soluble in water and insoluble in organic solvents.
Nitric acid: highly corrosive and toxic strong acid; used for the production of fertilizers, production of explosives, and as a component of aqua regia, as well as mixed acid for nitration of aromatic compounds Osmium tetroxide: in organic synthesis, is widely used to oxidise alkenes to the vicinal diols Oxalyl chloride
Both propellants are extremely dangerous individually: nitric acid is highly corrosive and releases toxic nitrogen dioxide during reactions, or even simply while exposed to air in its highly concentrated "red fuming" form, typically used as rocket propellant. UDMH is both toxic and corrosive. [2]
Strong acids/bases (nitric acid, sodium hydroxide), calcium oxide, anhydrous zinc chloride can be corrosive GHS05: Corrosive Explosives, divisions 1.5, 1.6; Flammable gases, category 2; Self-reactive substances and mixtures, type G (see HAZMAT Class 4 Flammable solids) Organic peroxides, type G; no pictogram required
Anhydrous nitric acid, referred to as white fuming nitric acid, can be used to prepare water-free nitration mixtures, and this method is used in laboratory scale operations where the cost of material is not of primary importance. Fuming nitric acid is hazardous to handle and transport, because it is extremely corrosive and volatile. For ...
Nitrogen dioxide is an acrid, corrosive brown gas. Both compounds may be easily prepared by decomposing a dry metal nitrate. ... Fuming nitric acid contaminated with ...
