What is the covalent compound formula for Nitric Acid?
It would be ##NO_2OH##
Imagine the ##N## with 5 valencies, in the centre. Four of those are taken by two double-bonded ##O##, and the fifth is taken by an ##OH##
In a watery environment, the ##H## is quickly 'donated' to a water molecule in the form of an ##H^+## to form the hydronium or acid ion ##H_3O^+##, leving the ##NO_3^-## ion.
