$HNO_2$ is a weak oxoacid.

Work Step by Step

To predict if an oxoacid is strong or weak, normally, we just need to calculate the difference between the number of oxygens, and the number of hydrogens: $HNO_2$: 1 "H" and 2 "O" - If that difference is $\geq 2$, this is probably a strong acid, otherwise, it is weak. 2 - 1 = 1 1 $\geq 2$ False Therefore, $HNO_2$ is a weak oxoacid.
