Some of the properties of strong and weak acids are different. All statements below are properties of weak acids except for:

b. Weak acids dissociate completely if the pH is raised

E. Weak acids dissociate completely at an pH

Generally, weak acids dissociates only slightly in water.

weak acids have a pKa,

weak acids and their salt with strong base acts as buffer solution.

Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization. Part A Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows: C5H5N+H2O⇌C5H5NH++OH− The...
