That sharp bite of lemon juice. The sour edge of yoghurt. The fizz of a soda. The burning pain of stomach acid. All of these sensations share one chemical explanation: ACIDS. Acids are among the most important and most common chemical substances on Earth in our food, in industry, in our own bodies. Today you meet Acids as a chemist does: you learn what defines an acid, how mineral acids differ from organic acids, where acids are found naturally, and how to recognise them in a laboratory. Lemon, vinegar, battery acid the chemistry starts now!
