hard soft acid-base
Molecular formula :

nature : pH is soft, acid-base reaction, said ease of a character. -- Negative low polarization, valence electron oxidation song is also easily give the body is soft base; Opposition to the donor base is hard. The atomic volume, low charge, the high rate of polarization, the price of electron shell loose grasp of acceptance body known as soft acid; In contrast, small size, charge high polarization rates, low price -- the one envisioned by the Chinese Table accepted as hard acid. Between the soft, acid known as acid-base junction.
