Question: are all arrhenius acids lewis acids?
Answer: By the Arrhenius definition: Acids release a proton, or H+, in water. ... Just as an Arrhenius acid is a Brønsted-Lowry acid, a Brønsted-Lowry acid is a Lewis acid. In the Lewis definition, acids are electron pair acceptors. As a result of this, the acid is able to form a covalent bond with whatever supplies the electrons.
