Acids and bases

The chemistry of acids and bases can appear wonderfully colourful, but occasionally mysterious to some students. Their understanding can be hindered by confusing language and a lack of appreciation of what exactly is happening in solution at the particle level. Getting to grips with the mathematical manipulations and logarithms required can lead some to perceive acids and bases as a tricky area of chemistry. The need to apply equilibria concepts or understand indicators at an advanced level can add to students’ worries.

Morag Easson considers common difficulties, confusing language, and which approaches and activities are available for teaching the chemistry behind acids and bases.
