(a) Interpretation: The most appreciate indicator for detecting the change in pH value from 7 to 5 needs to be determined. Concept introduction: The scale which is used to determine the acidity and basic nature of the water-based solution is called pH . The lower pH is observed in acidic solution while basic solutions contain a higher pH value.
