Strong Acids and Bases: Complete Dissociation
Captions available
The idea
A strong acid or base is one that reacts essentially completely with water, so its equilibrium lies so far toward products that the reaction is treated as one-directional.
In practice
Dissolving HCl in water leaves essentially no molecular HCl remaining, only H3O+ and Cl−.
Where people slip
"Strong" describes the extent of this reaction, not the solution's concentration — Chem 0406 registers that twin in full.
