Potassium hydroxide (KOH)almost completely dissociates in aqueous solution into K⁺ and OH^- and is therefore a A) strong acid. B) strong base. C) weak base. D) weak acid. E) nonpolar covalent molecule.

Question

Quizplus · Accepted Answer

Because potassium hydroxide dissociates completely and adds hydroxide ions (OH-) to an aqueous solution, it is a strong base. A weak base would not dissociate so completely. An acid would contribute hydrogen ions (H⁺) to an aqueous solution. Potassium hydroxide is an ionic compound; a nonpolar covalent molecule would not dissociate or dissolve in an aqueous solution.
