A solution of nitric acid, water and alcohol, nital, is used for etching metals to reveal the microstructure. ISO 14104 is one of the standards detailing this well known procedure. [45] Nitric acid is used either in combination with hydrochloric acid or alone to clean glass cover slips and glass slides for high-end microscopy applications. [46]
Nital is a solution of nitric acid and alcohol commonly used for etching of metals. It is especially suitable for revealing the microstructure of carbon steels. The alcohol can be methanol or ethanol. Mixtures of ethanol and nitric acid are potentially explosive. This commonly occurs by gas evolution, although ethyl nitrate can also be formed ...
Aqua fortis /spirit of nitre – nitric acid, formed by 2 parts saltpetre in 1 part (pure) oil of vitriol (sulfuric acid). (Historically, this process could not have been used, as 98% oil of vitriol was not available.) Aqua ragia /spirit of turpentine/oil of turpentine/gum turpentine – turpentine, formed by the distillation of pine tree resin.
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Less-common or obsolete hypergolic propellants include: Aniline + nitric acid (unstable, explosive), used in the WAC Corporal [25] Aniline + hydrogen peroxide (dust-sensitive, explosive) Furfuryl alcohol + IRFNA (or red fuming nitric acid) – Copenhagen Suborbitals SPECTRA Engine [26] [5]: 27 Furfuryl alcohol + WFNA (or white fuming nitric ...
Albertus Magnus, in the 13th century, documented the ability of nitric acid to separate gold and silver by dissolving the silver. [8] Indeed silver nitrate can be prepared by dissolving silver in nitric acid followed by evaporation of the solution. The stoichiometry of the reaction depends upon the concentration of nitric acid used.
Fuming nitric acid contaminated with yellow nitrogen dioxide. Nitric acid (HNO 3) is by far the most important and the most stable of the nitrogen oxoacids. It is one of the three most used acids (the other two being sulfuric acid and hydrochloric acid) and was first discovered by the alchemists in the 13th century. It is made by catalytic ...
Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3.It is a potassium salt of nitric acid.This salt consists of potassium cations K + and nitrate anions NO − 3, and is therefore an alkali metal nitrate.
