Laboratory Applications: Thymolphthalein is widely used as an acid-base indicator in laboratory experiments. Its mechanism of action involves a color change that is dependent on the pH of the solution. It is commonly employed in titrations to determine the endpoint of acid-base reactions. Storage...
It is concluded that the solubilization of thymolphthalein is accompanied by a shift in the acid-base equilibria in which this compound participates, as is reflected in the drop of its p K a value and the shift of the region of color change....
