Topic 8.1: Theories of acids and bases

8.1.1 Define acids and bases according to the Bronsted-Lowry and Lewis theories

A Bronsted-Lowry acid is a proton donor

A Bronsted-Lowry base is a proton acceptor

A Lewis acid is an electron pair acceptor

A Lewis base is an electron pair donor.

8.1.2 Deduce whether or not a species could act as a Bronsted-Lowry and/or a Lewis acid or base

All Bronsted-Lowry acids are Lewis acids

Not all Lewis acids are Bronsted-Lowry acids

The term Lewis acid is usually reserved for those species which can only be described by Lewis theory, that is those that do not release H+.

8.1.3 Deduce the formula of the conjugate acid (or base) of any Bronsted-Lowry base (or acid)
