Predict if the solutions of the following salts are neutral, acidic or basic: `NaCl, KBr, NaCN, NH_(4)NO_(3), NaNO_(2)` and `KF`

Explanation

Acidic, basic or neutral character of the salt can be decided on the basis whether they are salts of strong or weak acids or bases.
(i) NaCN, `NaNO_2`, KF are basic because they are the salts of strong base and weak acids.
(ii) `NH_4NO_3` is acidic because it is a salt of strong acid and weak base.
(iii) NaCl, KBr are neutral because they are salts of strong acids and strong bases.
