Best Answer

Calcium ions are neutral and hydrogencarbonate ions are: (!!) BOTH acid AND base at the same time, both very weakly, though it is a bit more base than acidic:

acid: HCO3- + H2O --> CO32- + H3O+ pKa=10.25
base: HCO3- + H2O -->H2CO3 + OH- pKb= 7.64

Ca(OH)2 (calcium hydroxide) is a strong base (which means it cannot be an acid). It is formed by mixing CaO (quicklime, or calcium oxide) with H2O (water).
