Hard acids have affinity towards hard bases and soft acids have affinity towards soft bases.


One can characterize a base/acid as a hard or soft based on the following:

1) Hard acids and hard bases:
-have high electronegativity, high oxidation state and low polarization ability.

2) Soft acids and soft bases
-have low electronegativity, low oxidation state and high polarization ability.
