You can make an aqueous solution of $ce{KSO_4^{-}}$ (and no other cations), in the sense that you can make a regular $ce{K2SO4}$ solution which lacks some potassium ions. By doing so, you are producing a solution with a net electric charge. The higher the net electric charge, the less stable the solution is, as electrons will start redistributing into the surroundings in order to correct the.
