Phenolphthalein is a weak organic acid, at room temperature, appearing as white or microstrip yellow small crystals, being odorless, tasteless, insoluble in water and soluble in alcohol (ethanol) and ether. When
The color change of the phenolphthalein, the indicator, at an end point can be explained in terms of which of the following? Why does a titrated sample that is fuschia with phenolphthalein turn colorless when the solution is blown into?
