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 ...
Lunar caustic/ lapis infernalis – silver nitrate, formed by dissolving silver in aqua fortis and evaporating. Lye – potash in a water solution, formed by leaching wood ashes. Potash – potassium carbonate, formed by evaporating lye; also called salt of tartar. K 2 CO 3; Pearlash – formed by baking potash in a kiln.
Methyl nitrate is a very strong explosive with a detonation velocity of 6,300 m/s, [8] like nitroglycerin, ethylene glycol dinitrate, and other nitrate esters. The sensitivity of methyl nitrate to initiation by detonation is among the greatest known, with even a number one blasting cap , the lowest power available, producing a near full ...

However, there is a report that the chemist Sebastian Moiseevich Tanatar produced sodium peroxynitrate octahydrate (NaNO 3 ·H 2 O 2 ·8H 2 O) by evaporating a solution of sodium nitrate and hydrogen peroxide until crystallisation begins and then mixing with alcohol to form crystals of the octahydrate. [3]
The color intensity of the resulting solution is then measured by a colorimeter and checked against a calibration curve to determine the nitrite ion concentration. [ 4 ] To analyze nitrate concentrations quantitatively, the sample is first passed through a copper-cadmium column to reduce the nitrate ions quantitatively to nitrite ions, and the ...
