$C_5H_{10}NH(aq) + HCl(aq) \lt -- \gt C_5H_{10}N{H_2}^+(aq) + Cl^-$
Hydrochloric acid: $HCl$ - When piperidine reacts with hydrochloric acid, it will happen a acid-base reaction, where the amine is going to receive a proton (So it is the base), and the $HCl$ is going to donate this proton (So it is the acid). - Normally, amines act as bases, because they have a lone pair that can be used to form a bond with the receiving proton.
