Derek is reading two different definitions of a base. An Arrhenius base is a chemical that increases the concentration of OH- in water, and a Bronsted Lowry base is a chemical that accepts a proton (H+.) Explain why using only the Arrhenius base definition in your Chemistry 12 course would not be adequate.
Arrhenius theory is known to be the most limited of the three theories since it requires the solutions to be aqueous. It only applies to substances that produce Hydrogen ions (H+) or hydroxide ions (OH−).For example if equal amounts of HCl and ammonia react, the solution is slightly acidic.
