Lemon juice is sour. Soap feels slippery. Both are in your kitchen, and they are very different. In this chapter we learn how to tell an acid from a base, what they do to metals and to each other, and what they have in common when they are in water. Then we meet the salts that they make, from the salt on your plate to baking soda and plaster of Paris. We measure acidity with the pH scale, and we use it to understand the stomach, the teeth and the soil. Python helps us with the numbers.

Acids and Bases
An acid tastes sour, and a base feels soapy, but you should never taste a chemical to find out. In this course we learn to use indicators, we see what acids and bases do to metals, carbonates and each other, and we find out what makes a substance an acid.
Salts and Their Uses
When an acid meets a base, a salt is made. Common salt is only one of the family. In this course we learn the salts of daily life: what is made from common salt, how baking soda and washing soda differ, and what plaster of Paris does.
