This means we are left with CH3NH3+, which we know will act as an acid (since it has a positive charge and will donate an H+.). Dimethylamine and trimethylamine are co-produced; the reaction kinetics Methylamine is a Bronsted base, as it can accept a proton from water. Answer: In short CH3CH2NH3Cl is acidic because it is formed from a strong acid (HCl) and a weak base (CH3CH2NH2). C H X 3 C H X 2 N H X 3 C l is acidic because it is formed from a strong acid ( H C l) and a weak base ( C H X 3 C H X 2 N H X 2 ). From the given options, CH3NH2 is weak base and its salt is CH3NH3Cl. For example, NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt is acidic.
