Which of the following is the correct Arrhenius definition of bases? A) A base is a substance that produces H⁺ ions in aqueous solutions. B) A base is a substance that reacts with OH^- ions in aqueous solutions. C) A base is a substance that decreases the amount of OH^- ions in aqueous solutions. D) A base is a substance that produces OH^- ions in aqueous solutions. E) A base is a substance that does not change the concentration of OH^- ions in aqueous solutions.

Question

Quizplus · Accepted Answer

The correct Arrhenius definition of bases is that they are substances that produce OH^- ions (hydroxide ions) in aqueous solutions. Option D correctly states this definition. Option A is incorrect because it refers to the production of H⁺ ions (hydronium ions), which is characteristic of acids. Option B is incorrect because it refers to the reaction of a base with OH^- ions in solution, rather than the production of these ions. Option C is incorrect because it refers to the decrease of OH^- ions in solution by a base, which is not a unique property of bases. Option E is incorrect because it suggests that bases have no effect on the concentration of OH^- ions in solution, which is incorrect as bases increase the concentration of hydroxide ions in solution.
