At the equivalence point, the moles of CH3NH2 equals the moles of HCl. Methylamine (CH3NH2) is a weak base and therefore cannot fully resist the tug of water molecules on the extra proton in the CH3NH3+ ion. You have to also make another equation that includes HCl to finally figure out equilibrium of $\ce{H^+}$, but I don't know how to get there. Elaborated Notice that this compound is ionic, comprising C H X 3 C H X 2 N H X 3 X + cation and C l X anion.
