What is Nitric Acid
The structure of nitric acid is planar, meaning the chemical structure is flat. There are two major resonance forms of nitric acid. Resonance form occurs when there are multiple ways of drawing the Lewis structure of a compound. A Lewis structure is a diagram that shows how atoms are bonded together and illustrates the presence of non-bonded pairs of electrons in a compound. The double-headed arrow drawn between the two resonance structures is there to show that there is more than one way to draw the structure.
