Answer:
A solution with a pH between 5 and 7 is neutral, 8 or higher is a base, and 4 or lower is an acid. Lime juice, lemon juice and vinegar are acids, so they should have turned the indicator solution red or purple color. ... An indicator, like anthocyanin, responds to the levels of hydrogen ions in the solution.
