WitrynaBaking soda and deionized water reacted with the red litmus paper, turning it blue—indicating a base, the pH taken from the pH meter was 8.0—slightly basic (pH > 7.0), and turned greenish- blue when reacting with the universal indicator—comparable to the known pH of 8.5. WitrynaLitmus is probably the most common acid-base indicator. If placed in relatively acidic solutions (pH < 5), litmus is red. In relatively basic solutions (pH > 8), litmus is blue. Notice that there is a range in which litmus is neither red nor blue (between 5 and 8).
