Question

Is the following acid-base reaction Arrhenius, Bronsted-Lowry, or Lewis: AlCl3 + Cl --> AlCl4-

Answer 1

It is a typical Lewis scheme.

`AlCl_4^-` is a "Lewis adduct", `AlCl_3` is the Lewis acid and `Cl^-` the Lewis base.

There aren't proton donors to talk of Brönsted-Lowry, nor hydroacids or oxoacids to talk of Arrhenius.

Hope this is useful.
