Consider the salt pyridinium acetate, [(C₅H₅NH⁺) (C₂H₃O₂^{1 -}) ],
That is derived from a combination of a weak acid , HC₂H₃O₂, and a weak base , C₅H₅N,
As shown below.
C₅H₅N + HC₂H₃O₂→[(C₅H₅NH⁺) (C₂H₃O₂^{1 -}) ] K _b(C₅H₅N) = 1.7×10^{- 9} and K _a(HC₂H₃O₂) = 1.8×10^{- 5} Which statement listed below is true?

The salt is derived from a weak base (pyridine, with Kb = 1.7×10^-9) and a weak acid (acetic acid, with Ka = 1.8×10^-5). Since the acid is stronger than the base (as indicated by a larger Ka value compared to Kb), the resulting solution of the salt in water will be acidic.
