A blueberry indicator works by using the natural pH sensitivity of anthocyanins, the pigments found in blueberries. When the pH of a solution changes, these pigments shift in color; for instance, they appear red in acidic conditions and blue in alkaline ones. This property allows blueberries to serve as a natural pH indicator, providing a visual representation of the acidity or alkalinity of a solution. Thus, by adding blueberry juice to a solution, one can estimate its pH level based on the resulting color change.
