# Can a strong electrolyte be sparingly soluble? [duplicate]

A strong electrolyte is an electrolyte that completely, or almost completely, ionizes or dissociates in a solution. My book has a question:

In a saturated solution of sparingly soluble strong electrolyte $\ce{AgIO3}$ the equilibrium with sets in is $\ce{AgIO3→Ag+ + IO3-}$

Is the above statement wrong or is there anything as sparingly soluble strong electrolyte?
