      Thymolphthalein is an acid-base (pH) indicator. Its transition range is around pH 9.3-10.5.
Below this pH, it is colorless; above, it is blue. Thymolphthalein is also known to have use as a
laxative and for disappearing ink.

Function:

Thymolphthalein is an acid-base (pH) indicator. Its transition range is around pH 9.3-10.5.
Below this pH, it is colorless; above, it is blue. Thymolphthalein is used as a visual indicator
for the pH of swimming pools, changing the water blue when the pH increases, it can be
used to detect the presence of urine being introduced into the normally neutral pH of the
water. The molar extinction coefficient for the blue thymolphthalein dianion is
38,000M−1cm−1 at 595nm.
