The Recognized Strong Acids and Bases, Identified Structurally
Captions available
The idea
The short strong acid and base list is fixed by structure, not memorized values.
In practice
HCl, HBr, HI, HNO3, H2SO4, and HClO4 form the strong acid set; the group 1 hydroxides (LiOH, NaOH, KOH) and the soluble group 2 hydroxides (Ca(OH)2, Sr(OH)2, Ba(OH)2) form the strong base set.
Where people slip
Every acid outside this list is weak by default, including the familiar but weak HF.
