Edexcel IAL Chemistry A2 14.13 pH data from acid and base experiments
Read the table or ranking first, then connect pH differences to complete dissociation, partial dissociation, dilution behaviour or hydroxide ion production.
How this is tested
- Explain why tenfold dilution changes strong-acid pH by 1 but weak-acid pH by less.
- Rank base pH by strength, concentration and the number of hydroxide ions produced.
