$NH_{4}NO_{3}$ has pH<7

Explanation:

pH of salt depends on species generated through hydrolysis of the given salt.

Hydrolysis equilibrium of $NH_{4}NO_{3}$ is given below:

$NH_{4}NO_{3}+H_{2}O\rightarrow NH_{4}OH+HNO_{3}$

$NH_{4}OH$ is a weak base and $HNO_{3}$ is a strong acid. So species obtained through hydrolysis of $NH_{4}NO_{3}$ is a mixture of strong acid and weak base.

Hence the the salt solution will be acidic in nature. That means pH of solution is less than 7.
