HN03 Full Form

What is the full form of HN03?

HNO_3 is the abbreviation used for the chemical solution named Nitric acid. This chemical is also known as the spirit of niter and aquafortis. The chemical structure of this compound shows that it is inorganic, which means that carbon and hydrogen bonds are missing. The compound is usually colourless in nature, but it aquires a yellow shade as it ages. This yellow shade is due to the process of decomposition, which results in the formation of nitrogen oxides. These chemicals have a very suffocating odour which is also very toxic if inhaled. The taste of this compound is bitter. As this is an acid, a base like sodium bicarbonate can be used during neutralisation reactions.

Kinds Of Nitric Acid

Usually, the kind of nitic acid commercially available will have 68% of water content in it. The water content sometimes measures up to 68%, thus calling it fuming nitric acid. Fuming nitric acid can again be divided into red-fuming nitric acid and white-fuming nitric acid.

Structure Of Nitric Acid

This chemical contains 3 oxygen atoms, 1 hydrogen atom, and 1 nitrogen atom. Here, one oxygen atom is connected with a double bond to the nitrogen atom in the center position. The other oxygen atom has a single bond with the nitrogen atom. This oxygen atom also has a single bond to a hydrogen atom. The leftover oxygen atom is also singly bonded with the nitrogen atom at the center. This oxygen atom has a charge of -1. The central nitrogen atom consists of a charge of +1. These charges, -1 and +1, cancel out each other.
