Web4 okt. 2024 · This observation has eventually led to a classification system called Hard and Soft Acids and Bases (HSAB). 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.
