Dissociation equation for C6H5NH3+?

The problem says to write the dissociation equation for C6H5NH3+ including water as a reactant.

Would it be this?

C6H5NH2 + H20 --> C6H5NH3+ + OH-

That's not exactly C6H5NH3+ dissociating but I don't understand how a positively charged thing can react with water.

  • Water can act as an acid or base depending on the other reactant. In this case, water would act as a base in which it would accept a proton from C6H5NH3+ to form the hydronium ion H3O+. You're left with an amine and the hydronium ion for products.

    C6H5NH3+ + H2O ---> C6H5NH2 + H3O+

  • Water is a weak base, but it is a base, so it can react with water. Check out my picture.

    Hope I helped!

  • C2H5NH2 + H2O ↔ C2H5NH3 + OH-
