E)accepts hydronium ions from other substances.

Question

Quizplus · Accepted Answer

A Brønsted-Lowry base accepts protons from other substances, while an acid donates protons to other substances. Therefore, choices A and B are incorrect because they describe acids, not bases. Choice C is partially correct, as a Brønsted-Lowry base can donate electrons as well as protons, but since it does not specifically mention proton donation, it is not the best choice. Choice E is also incorrect because hydronium ions are simply hydrated hydrogen ions (H3O+), so accepting hydronium ions would be the same as accepting hydrogen ions.
