Predict if the solutions of the following salts are neutral,acidic,or basic: $NaCl, KBr, NaCN, NH_4NO_3, NaNO_2$ and $KF$.

(N/A) $1$. Neutral solutions: $NaCl$ and $KBr$ are salts of a strong acid and a strong base,so their solutions are neutral.
$2$. Acidic solutions: $NH_4NO_3$ is a salt of a strong acid $(HNO_3)$ and a weak base $(NH_4OH)$,so its solution is acidic.
$3$. Basic solutions: $NaCN, NaNO_2$ and $KF$ are salts of a weak acid and a strong base,so their solutions are basic.
