Brønsted-Lowry Question

Question

Acid or base?

1.) (CH3)2NH+H2O→(CH3)2NH+2+OH−

2.) C6H5NH2+H2O→C6H5NH+3+OH−

3.) C6H5CH2NH2+H2O→C6H5CH2NH+3+OH−

Answer 1

I think there are some typos in the equations which we can touch on but basically all of them produce hydroxide (OH-) in solution, which makes them chemical Arrhenius bases. They also all accept hydrogens, which makes them Bronsted Lowry bases as well.
