#### Answer

A $[CH_3NH_3]NO_3$ solution will be acidic.

#### Work Step by Step

1. Identify the strength of each ion in the salt: $CH_3N{H_3}^+$: Weak acidity. - Since $CH_3N{H_3}^+$ is the conjugate acid of a weak base $CH_3NH_2$, it has a weak acidity. $N{O_3}^-$: Insignificant basicity: - Since $N{O_3}^-$ is the conjugate base of a strong acid: $HNO_3$, it has a negligible basicity. Therefore, since the stronger ion is an acid, the solution will be acidic.
