At what pH is this color change visible? When using bromothymol blue as the indicator, what is the pH of the solution when the concentration ratio of the acid to base form of the indicator is 1.4? (pK_a of bromothymol blue = 7.10) The indicator ...
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....
