Recap of Lecture 5 Acids Bases II
Strong acids dissociate completely to H and
conjugate base.Know the strong acids. Weak acids
dissociate partially.Use equilibrium
calculation Ka Strong bases dissociate
completely to OH- and counterion. Weak bases
dissociate partiallyUse equilibrium calculation

acids are strong electrolytes. Weak acids are
weak electrolytes.
