Strength, Electrolytic properties and
Conductivity
Because
strong acids undergo complete dissociation, they are better conductors of
electricity in solution than weak acids, they are stronger electrolytes than
weak acids.
An
electrolyte is a compound which in solution conducts electricity.
Free
floating ions are responsible for conduction of electricity by a
solution.
Equal concentrations of strong and weak acids, because of the different
degree of dissociation, contain different concentration of ions—a
strong acid contains higher concentration of ions leading to
better conductivity.
Similarly, bases (hydroxides) which
dissolve in water (all hydroxides of Group IA metals and Ca, Sr,
and Ba) are strong electrolytes.
