Xylenol Blue is a sulfonephthalein dye. It exhibits observable color changes in response to variations in pH. Xylenol Blue undergoes two distinct color transitions across two specific pH ranges: an acidic range and an alkaline range. In a neutral solution, Xylenol Blue appears yellow (at pH 8); in a strongly acidic medium, its color shifts to red (at pH 2.8); and in an alkaline medium, the yellow hue transitions to blue (at pH 9.6) .
