WebApr 2, 2024 · History of Base. In 1884, Arrhenius proposed that a base is a substance that dissociates in an aqueous solution to produce hydroxide ions (OH−). These hydroxide ions can react with the hydrogen ions (H+, as per Arrhenius) from the dissociation of acids to produce water in an acid-base reaction. Therefore, a base is a metal hydroxide such as ...
