First of all, C5H5N is a base, not an acid and is also known as Pyridine, an organic compound similar to benzene in structure. It is very weak as a base though because it does not dissociate very much as all. In order for a compound to be a strong acid or base, it my ionize and dissociate completely in water, and the only bases that do this are metal hydroxides with metals in groups I and II (Except for Magnesium and Beryllium).
