Thymolphthalein is a kind of PH indicator.
It is a white to off white powder, insoluble in water.
The range of PH change is 9.4-10.6, and the color changes from colorless to blue.
It is also often combined with other indicators to form a gentle indicator, which makes the color change range narrower and the observation clearer. |
