8.1 Theories of acids and bases
8.1.1 Define acids and bases according to the Bronsted-Lowry and Lewis theories.
8.1.2 Deduce whether or not a species could act as a Bronsted-Lowry and/or a Lewis acid or base.
8.1.3 Deduce the formula of the conjugate acid (or base) of any Bronsted-Lowry base (or acid).
8.2 Properties of acids and bases
8.2.1 Outline the characteristic properties of acids and bases in aqueous solution.
8.3 Strong and weak acids and bases
8.3.1 Distinguish between strong and weak acids and bases in terms of the extent of dissociation, reaction with water and electrical conductivity.
8.3.3 Distinguish between strong and weak acids and bases, and determine the relative strengths of acids and bases.
8.4 The pH scale
8.4.1 Distinguish between aqueous solutions that are acidic, neutral, or alkaline using the pH scale.
8.4.2 Identify which of two or more aqueous solutions is more acidic or alkaline using pH values.
8.4.3 State that each change of one pH unit is a 10 fold change in the hydrogen ion concentration [H+(aq)].
8.4.4 Deduce changes in [H+(aq)] when the pH of a solution changes by more than one pH unit.
