Write down the equation for the reaction of aniline with hydrochloric acid. How does the valence of nitrogen change during this reaction?

Aniline or phenylamine has the formula C6H5NH2. The amino group -NH2 is a derivative of ammonia NH3.
C6H5NH2 + HCl = (C6H5NH3) Cl,
C6H5NH2 + H (+) + Cl (-) = C6H5NH3 (+) + Cl (-)
During the reaction, dissolution of aniline, a yellow oily liquid, is observed. Because a soluble salt is formed – phenylammonium chloride. Since this is an ion exchange reaction, neither the valences nor the oxidation states of the elements will change and the oxidation state of nitrogen will remain minus three, which means that its valence will be equal to three.
