HSAB is widely used in chemistry for explaining stability of compounds, reaction mechanisms and pathways. It assigns the terms 'hard' or 'soft', and 'acid' or 'base' to chemical species. 'Hard' applies to species which are small, have high charge states … See more Essentially, the theory states that soft acids react faster and form stronger bonds with soft bases, whereas hard acids react faster and form stronger bonds with hard bases, all other factors being equal. The classification in the … See more If the interaction between acid and base in solution results in an equilibrium mixture the strength of the interaction can be quantified in terms of an equilibrium constant. … See more In 1983 Pearson together with Robert Parr extended the qualitative HSAB theory with a quantitative definition of the chemical hardness (η) as being proportional to the second derivative of the total energy of a chemical system with respect to changes in the number of … See more An application of HSAB theory is the so-called Kornblum's rule (after Nathan Kornblum) which states that in reactions with See more • Acid-base reaction • Oxophilicity See more

WebThe HSAB (Hard Soft Acid Base) theory categorizes chemical species as acids or bases and as “hard”, “soft”, or “borderline”. It explains that soft acids or bases tend to be large and very polarizable, while hard acids or bases …
