Thymol Blue, Indicator
Description:
Thymol Blue is a pH indicator that undergoes a color change over a broad pH range, typically used for titration and pH testing. It is a sulfonphthalein dye that shifts color in response to changes in acidity or alkalinity. Thymol Blue is commonly employed in acid-base titrations and other applications where monitoring pH shifts is essential.
