Answer:
Red and blue litmus paper will not give you anything but a pH range, if blue turns red, it is an acid (pH below 7) and if it doesn’t change color it is a base (pH above 7). Red litmus turns blue in a base, and doesn’t change in an acid. If neither changes, the pH is approximately 7 ( a neutral substance such as water). To find the pH you really need to use pHydrion paper or purple cabbage juice.
