FREE Expert Solution

We are asked which statement is false about the following acid-base reactions. 


Let’s define a Bronsted-Lowry Acid and a Bronsted-Lowry Base.

Bronsted-Lowry acid → proton (H+) donor

Bronsted-Lowry base → proton (H+) acceptor


Based on the Lewis definition:

Lewis acid is an electron pair acceptor.

Lewis base is an electron pair donor.
