WebFor many practical purposes it is more convenient to discuss the logarithmic constant, pKa pKa = -log10 Ka The larger the value of pKa, the smaller the extent of dissociation at any given pH - that is, the weaker the acid. A weak acid has a pKa value in the approximate range -2 to 12 in water. Webn -Butylamine is a weak base. The pK a of [CH 3 (CH 2) 3 NH 3] + is 10.78. [4] n -Butylamine exhibits reactions typical of other simple alkyl amines, i.e., alkylation, acylation, condensation with carbonyls. It forms complexes with metal ions, examples being cis - and trans - [PtI 2 (NH 2 Bu) 2 ]. [5] Uses [ edit]
