Acids, Alkalis & pH

Define acids and alkalis in terms of hydrogen ion concentration, describe the pH scale (0–14), and explain how indicators are used to identify and measure acidity or alkalinity

How to tell they’ve got it

Tick these off as you see them — no test required.

Try this together

If your child used a piece of universal indicator paper to test lemon juice and baking soda solution, could they predict what colour each would turn and explain what that tells you about each substance?
