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. Web14 de jun. de 2024 · I know that Brønsted–Lowry acids can donate a proton and a Brønsted–Lowry base can receive a proton.

Lewis acid/base is a electron reciever/donor respectively. While a Bronsted Acid/base is a proton donor/acceptor. Usually in general chemistry, you focus on Bronsted Acid/bases. Using the Bronsted model, we must find whether the the compound donates a proton, receives a proton, or neither.
