Question

Quizplus · Accepted Answer

A Brønsted-Lowry acid is defined as a substance that donates protons to other substances. This is the correct definition of a Brønsted-Lowry acid and distinguishes it from a Brønsted-Lowry base, which accepts protons. Choices A and B are incorrect because a Brønsted-Lowry acid does not necessarily produce hydrogen ions or hydroxide ions in aqueous solution, respectively. Choice D is incorrect because a Brønsted-Lowry acid donates protons rather than accepts them. Choice E is incorrect because a Brønsted-Lowry acid does not necessarily accept hydronium ions from other substances.
