phenol is more acidic because of the benzene ring present in the molecule,when you lose the H form the OH group it is possible to delocalise the charge around the aromatic system due to the pi electron cloud,straight chain alcohols cannot do this so it is less favourable to deprotonate them hance it is easier to deprotonate a phenol,hence we say it ...
Phenolphthalein is used in titrations mostly to indicate the pH of the solution. If acidic solutions are added with this chemical they become colorless. If the acidic solutions are already colorless, they remain colorless after its addition too.Strong acidic solutions appear in orange color with phenolphthalein.The basic solutions appear pink in color.If the concentration of phenolphthalein in solution is more, then it can give purple color to the basic solutions. The pink color of this indicator in basic solutions gradually fades away and the solution becomes colorless after sometime.Phenolphthalein is not soluble in water and hence the solution of it is generally prepared using alcohol. Phenolphthalein solution is itself a weak acid and loses hydrogen ion in the solution.he pink color of this indicator in basic solutions gradually fades away and the solution becomes colorless after sometime.
