Within the study of Acid, Base, pH, this concept is well-established through extensive research and is documented in standard scientific literature. The specific properties, mechanisms, or characteristics of The concentration of H⁺ and OH⁻ are always equal in pure water directly address what is being asked. Among the other options, It is an exothermic reaction, It does not occur at high temperatures, and The concentration of H⁺ is always greater than OH⁻ do not correctly answer this question because they either refer to different concepts, describe properties of other molecules or processes, or represent common misconceptions about this topic.
