Consider this: Carbonic acid, H2CO3 is a weak acid. The conjugate base of a weak acid is a strong base. Thus the carbonate ion is a strong base. Since all group I compounds are soluble, potassium carbonate dissociates into K+ and CO32-ions, just like carbonic acid. (But technically carbonic acid is unstable and decomposes into water and carbon dioxide.)
