ACS Grade Thymolphthalein

Product Description

Product Description:

Thymolphthalein is a white powder that is dissolved into a clear, colorless liquid when added to isopropyl alcohol. An acid base indicator, it turns a brilliant magenta color when it comes in contact with basic solutions like sodium hydroxide or ammonia hydroxide, and returns to clear when an acid is introduced to the solution, balancing out the pH. Thymolphthalein is an acid-base indicator which is colourless in acidic form and deep blue in basic form. Acidic form retains hydrogen on each hydroxyl group.
