The pH of a $NaNO_3$ solution will be equal to 7. This happens because, this salt is formed by a insignificant acid $(Na^+)$ and an insignificant base $(N{O_3}^-)$, therefore, the solution is neutral.
To predict the pH range of an salt: 1. Identify the ions that form this salt, and compare their strengths: 1 $Na^{+}$: Conjugate acid of a strong base $(NaOH)$: Insignificant acid. 1 $N{O_3}^-$: Conjugate base of a strong acid $(HNO_3)$: Insignificant base. Since there is no significant electrolyte, the solution is neutral.
