Attributes of Nitric Acid
Physical attributes: In its most common type nitric acid is usually a smelly, clear liquid and pure (anhydrous) that boils at 83oC and solidifies at -42oC. It is actually employed in varying dilutions across a lot of industries and chemical processes from munitions thru to farming, cleaning up and woodwork.
As a pure acid HNO3 regularly emits white-colored vapor when exposed to air and as a dissolved solution may give off a smoke which is ruddy-brown resulting in its typical name €red fuming acid'. When kept in a diluted variety for some length of time the acid usually takes on a yellow tinge.
Nitric acid is entirely soluble in water.
This mineral based acid is highly corrosive, even in dilute forms, and if splashed on skin will result in yellow blisters to be formed - these needs to be expunged instantly with large quantities of water. It's exceptionally toxic.
100 % pure anhydrous nitric acid (i.e. undiluted) isn't, however, stable and also at ambient temps can decompose, as temperature raise also does the speed of the acid's breaking down and when warmed up vigorously it will eventually divide into its component form of h2o, oxygen and nitrogen dioxide. Proper care is necessary, therefore in its storage space and dealing with.
Chemical qualities: Nitric acid can be viewed to get a variety of attributes that can be details as reactive, oxidizing, acidic and as passivation.
Its acidic nature implies that varying levels of corrosion can be expected dependent on the amount of dilution - resulting in its use as a cleansing, etching and €ageing' substance in many applications. If being employed as a reagent or cleanser then proper care must be taken to use vessels produced from corrosion resistant alloys or metals to allow processes to develop.
As a robust and highly effective oxidizing agent it reacts, in some cases powerfully and violently, with lots of non-metallic elements and compounds and the resultant reaction can be an explosive one. This holds true to a lot of metals with the exception of those considered as €precious' in fact it is for that reason that nitric acid can be used in the cleansing and evaluating of precious metal purity. Based on the degree of dilution implemented during oxidization nitrous oxide could be created.
When employed in addition to many metals the end result is that nitric acid is going to dissolve many of them and in the process produces nitrogen oxides. If joined with hydrochloric acid then Nitric acid could be used to dissolve what is known as €noble' metals for instance gold, iridium, platinum and others.
As it is corrosive in nature, when employed on iron, aluminum and chromium in a concentrated type nitric acid is likely to form a layer of metallic oxide that prevents further oxidation - an operation generally known as passivation.
