Nitric acid $(HNO_3)$ is the conjugate partner of $N{O_3}^-$.
1. Identify if the substance is an acid or a base (or both): - $N{O_3}^-$ is a base. 2. Since $N{O_3}^-$, add one proton to it: - Add one hydrogen and sum one to the charge: $N{O_3}^- -- \gt HNO_3$ - This is the conjugate acid of $N{O_3}^-$. 3. Name it: $N{O_3}^-$: Nitrate ion. "ate" ions $-- \gt$ "ic" acids. Therefore : $HNO_3$ = Nitric acid.
