Phenolphthalein colour change
Phenolphthalein Colour Change. Between strongly acidic and slightly basic conditions the lactone form hin is colorless. Phenolphthalein adopts at least four different states in aqueous solution as a result of ph changes. The color change in phenolphthalein is a result of ionization and this alters the shape of the phenolphthalein molecules. Also it turns in pink colour in an alkaline solution or base.
Acid Base Indicators From chemguide.co.uk
The color change of a ph indicator is caused by the dissociation of the h ion from the indicator itself. Phenolphthalein changes colour at a ph above 7. It so happens that the phenolphthalein has finished its colour change at exactly the ph of the equivalence point of the first half of the reaction in which sodium hydrogencarbonate is produced. Colour change of phenolphthalein. Moreover the compound remains colourless in acids but starts to turn pink on ph 8 2 and continues to turn bright purple in strong bases. The natural colour of phenolphthalein is colourless.
In acidic solutions it is colorless.
Also it turns in pink colour in an alkaline solution or base. In acid solution phenolphthalein indicator gives colourless. Under strongly acidic conditions it exists in protonated form hin providing an orange coloration. Phenolphthalein is naturally colourless and works differently then litmus paper. Phenolphthalein c 20 h 14 o 4 an organic compound of the phthalein family that is widely employed as an acid base indicator. It is also suitable for titrations of weak acids and strong bases which have an equivalence point at a ph above 7 methyl orange changes colour at a suitable ph.

As an indicator of a solution s ph phenolphthalein is colourless below ph 8 5 and attains a pink to deep red hue above ph 9 0. Phenolphthalein adopts at least four different states in aqueous solution as a result of ph changes. It is also suitable for titrations of weak acids and strong bases which have an equivalence point at a ph above 7 methyl orange changes colour at a suitable ph. Recall that ph indicators are not only natural dyes but also weak acids. As an indicator of a solution s ph phenolphthalein is colourless below ph 8 5 and attains a pink to deep red hue above ph 9 0.
