Define an Arrhenius acid. A) an electron pair donor B) an electron pair receiver C) produces H⁺ ions in aqueous solution D) accepts H⁺ ions E) produces OH^- ions in aqueous solution

Question

Quizplus · Accepted Answer

An Arrhenius acid is defined as a substance that produces H+ (or H3O+) ions in aqueous solution. Hence, option C is the correct choice as it represents such a substance. Option E produces OHS- ion which is a base, and hence it cannot be an Arrhenius acid. Options A and B describe Lewis acids and bases, which are defined in terms of electron-pair donation and acceptance rather than the production or acceptance of H+ ions. Option D produces HS- ion which is a base; therefore, it cannot be an Arrhenius acid.
