What color do you predict phenolphthalein to turn when added to 10 ml of 0.1 M HCl? Why does phenolphthalein change color when going from an acid to a basic solution? Phenolphthalein is an indicator that changes
Phenolphthalein is an indicator that changes colour to pink/purple between pH 8 to 10, however, neutralization occurs when pH = 7. Why can phenolphthalein still be used as the indicator during a stron What is the color of phenolphthalein in a basic solution?
