Question

How is the Brønsted-Lowry theory of acids similar to the Arrhenius theory, and how is it different?

Answer 1

$\mathfrak{\huge{\red{\underline{\underline{ANSWER :}}}}}$

The difference between the three theories is that the Arrhenius theory states that the acids always contain H+ and that the bases always contain OH-. While the Bronsted-Lowry model claims that acids are proton donors and pron acceptors so bases do not need to contain OH- so acids donate a proton to water forming H3O+.
