Final answer:
KClO₃ is neither an acid nor a base, it is a salt from a strong acid and a strong base, and in water, it is a strong electrolyte that dissociates into ions.
Step-by-step explanation:
KClO₃, or potassium chlorate, is not an acid or a base; rather, it is a salt derived from the reaction of a strong base (KOH, potassium hydroxide) and a strong acid (HClO₃, chloric acid). When KClO₃ is dissolved in water, it disassociates into K+ and ClO₃- ions. Since both the components come from strong counterparts, the resulting solution of potassium chlorate is essentially neutral in water. Therefore, KClO₃ is neither a strong nor weak acid or base. Based on the given choice set, KClO₃ would be a strong electrolyte because it dissociates into ions almost completely in an aqueous solution.
