- 0 Start here A roadmap: the shelf gets a number and a cause, then salts and crystals. · 3 min You are here
- 1 The shelf again Two litmus strips together name a group. A blue strip alone cannot tell base from neutral. · 6 min
- 2 What acids have in common Every acid frees H⁺ ions in water, and a base that dissolves frees OH⁻ ions. · 7 min
- 3 Acids, bases and metals A reactive metal gives a salt and hydrogen with a dilute acid. A carbonate gives CO₂. · 8 min
- 4 The pH scale pH usually runs from 0 to 14: below 7 acidic, above 7 basic, and lower means more H⁺. · 8 min
- 5 pH in living contexts A mouth, a body, rain and a sting each have their own pH range. · 7 min
- 6 Salts from neutralisation An acid and a base make a salt and water, and common salt is the start of four useful chemicals. · 8 min
- 7 Crystals that carry water Some crystals hold water in their structure. Heat drives it out and water brings it back. · 7 min
- 8 The big picture Seven ideas from one shelf: the number, the cause, the salts and the crystals. · 4 min
- 9 Track quiz Seven quick questions, one for each lesson. Use the table if you get stuck. · 8 min
