Question

What is the covalent compound formula for Nitric Acid?

Answer 1

It would be `NO_2OH`

Explanation:

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.
