Edexcel IGCSE Chemistry 2.29 pH scale
Practise pH-scale questions by classifying values, explaining indicator colours and using pH 7 as the neutral reference point.
How this is tested
- Classify pH values as strongly acidic, weakly acidic, neutral or alkaline.
- Suggest pH values from solution type, indicator colour or ion evidence in the question.
- Use pH 7 as neutral and 11-14 as strongly alkaline when interpreting data.
