Question

Quizplus · Accepted Answer

An Arrhenius base is a substance that produces hydroxide ions (OH⁻) in solution. This is the definition proposed by Swedish chemist Svante Arrhenius. Options A and E refer to substances that donate or accept hydrogen ions, respectively, which are characteristics of acids and not bases. Option C is a general definition of a Lewis base, which includes substances that can donate or share a pair of electrons. Option D refers to a reaction between an acid and a base rather than the properties of a base alone.
