What are borderline acids and bases?
Moreover, what are hard and soft acid and base?
Lewis bases can be divided into two categories: hard bases contain small, relatively nonpolarizable donor atoms (such as N, O, and F), and. soft bases contain larger, relatively polarizable donor atoms (such as P, S, and Cl).
Besides, is nitrogen a hard or soft base?
In a nutshell, smaller or more highly charged metal ions are called hard acids. They are more likely to bind to hard bases, which typically have small donor atoms such as oxygen or nitrogen. Typical hard acids are titanium(IV), tantalum(V), magnesium(II) and lithium(I).
Application of HSAB to predict the direction of Inorganic reactions: HSAB principle is used to predict the outcome of few of the reactions. We can predict whether a reaction proceeds to the right or left based on soft or hard acid/base interactions.
