How acidic is lemon juice? How basic is soap? The pH scale gives a number. In this course we learn the scale, we see why it matters for the stomach, the teeth, the soil and insect stings, and we calculate how much acid neutralises a base.

Why does the pH scale go in steps of ten? Why is vinegar a weak acid and hydrochloric acid a strong one, when both turn litmus red? How does a chemist find the strength of an unknown alkali with a burette? In this course you read further, solve problems on pH, dilution and titration, and then take a timed challenge.
