Arrhenius vs Bronsted-Lowry

[BriannaDis2C]

What is the determining difference between Arrhenius Acids and Bases versus Bronsted-Lowry Acids and Bases?

[Natalie Swerdlow 3K]

Arrhenius acids defines acids as releasing a proton, or H+, into H2O as it dissociates and says that bases release a hydroxide ion, or OH- in H2O. Essentially, the acid will increase the concentration of H+ as it dissociates in water while the base will increase the concentration of OH- as it dissociates in water. Bronsted-Lowry goes further than the Arrhenius definition to describe an acid as a proton donor to any substance and says that the base is a proton acceptor from any substance, not just with water.
