WebMay 1, 2024 · Softness roughly refers to the polarizability of an acid or base. The larger and more neutral any species, the softer it is. Conversely, the smaller and more charged a species is, the harder it is. HSAB theory is a useful tool to predict thermodynamic stability or kinetic lability of Metal-Ligand complexes. WebMay 15, 2016 · Sorted by: 20. Both ammonia is a weak base and ammonium ion is a weak acid. Many, even most, acid/base conjugate pairs are like that. We should be using comparative instead of absolute adjectives in the rule about conjugate acid-base strengths: A weaker acid has a stronger conjugate base, not necessarily a totally strong one.
