Arrhenius acids and bases (article) Khan Academy

WebMar 18, 2024 · The Swedish chemist Svante Arrhenius developed the first chemical definitions of acids and bases in the late 1800s. Arrhenius defined an acid as a compound that increases the concentration of hydrogen ion (H +) in aqueous solution. Many acids are simple compounds that release a hydrogen cation into solution when they dissolve. WebReading the pH scale. The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.
