Aqueous Reactions and Solution Stoichiometry (Chapter 4)
... Most acids and bases are weak… they are only partially dissociated in water. Strong acids and bases dissociate almost completely in water. Since there are so few strong acids and bases, it is easier to remember which common acids and base are strong rather than trying to learn rules to determine whe ...
