Anthocyanin is a pigment found in nature and it has interesting properties. Red cabbage is a
vegetable that contains this pigment. When the cabbage is boiled or blended it releases the
water- soluble pigment. This pigment has a purple color to it when it is dissolved in water
(around the pH of 7) and it will act as a pH indicator. Although when it is mixed with a strong
base it turns blue and with a strong acid it turns red. There are also different shades of
colors in between the two extremes so it acts a little like a universal indicator solution and
shows you roughly what pH a substance has.
