Answer
Acid-base.
$CH_{3}$$NH_{2}$ + $H_{2}$$SO_{4}$ --> $CH_{3}$$NH_{3}^{+}$+ $HSO_{4} ^{-}$
Work Step by Step
Amines react with strong acids to form ammonium salts.
Nitrogen gains hydrogen from a strong acid. This is an example of an acid-base reaction.
$CH_{3}$$NH_{2}$ + $H_{2}$$SO_{4}$ --> $CH_{3}$$NH_{3}^{+}$+ $HSO_{4} ^{-}$
