turning from colorless to red. When the phenolphthalein reagent is dropped into water or neutral, acidic aqueous solution, there will be white turbidity. This is due to that the alcohol is easily soluble in water, so that the reagent water-insoluble phenolphthalein is precipitated out. The other...
It is soluble in alkaline solution, exhibiting red color in alkaline solution, but is colorless in acidic solution. The three benzene rings in the phenolphthalein molecule are linked to the carbon atoms of a sp3 hybrid center, and there is no conjugate relationship between the benzene rings, ...

a white poisonous acidic compound present in tars from coal and wood that when dissolved to make a weak liquid mixture is used as a disinfectant phenolphthaleinnoun a white or yellowish white compound used as a laxative and as an acid-base indicator because its solution is brilliant red in alk...
In basic solution,the acidic proton in the phenolphthalein will be captured by the hydroxide ions and forms a quinoid structure which is pink in colour. So, this appearance of pink colour will help to identify the end point of this titration. ...
1.) phph is itself acidic and small quantities are used in relatively large solutions to indicate pH qualitatively. A drop of phph on the surface of soap is too concentrated, and soap isn't a solution. You can dilute a small quantity of soap in water and then test with phph and ...
Introductionphenolphthalein is a weak organic acid, white or yellow tiny crystals at room temperature, odorless, tasteless, insoluble in water and soluble in alcohol (ethanol), ether. Dissolved in alcohol solution to make acid-base indicator, colorless in acidic solution, red in alkali or alkali ...
Odorless. Aqueous solution is acidic. Colorless to pH 8.5; pink to deep-red above pH 9. Colorless in presence of large amounts of alkali. Tasteless.Phenolphthalein is an organic compound used as a laboratory reagent and pH indicator. Phenolphthalein exerts laxative effects ...
