Answer
Potassium is not extracted from it's aqueous salt solution by electrolysis as aqueous solution will contain H+ ion along with metal ion. On the passage of electric current the H+ ion gets discharged in preference to metal. Thus, the product formed at cathode is hydrogen gas and not the metal.
