[PDF] Chemical Equilibrium and Le Châteliers Principle - Kingsborough
Acid-base indicators are materials that change color to reflect changes is solution acidity But when the solution becomes basic (the concentration of –OH ions is greater than the concentration of H+ ions) phenolphthalein solutions are pink The phenolphthalein is reflecting the acidity of the solution it is in
