Because both of them have ions!


To conduct electricity, we require charged particles. In metals, free electrons are the charged particles which make it possible for electricity to be conducted.

Similarly, for acids and bases, there are ions. Note that they will only conduct electricity in their aqueous state, since the ions are mobile in this state.

Often, acids produce the #H^+# ion, which combines with a water molecule and is, therefore, correctly written as an #H_3O^+# ion.

Similarly, bases often produce the #OH^-# ion in its aqueous state.
