Phenolphthalein turns pink as NaOH is a strong alkali
Phenolphthlalein is something like a pH indicator. When it is added to a liquid and the liquid turns pink, it means that the latter substance is basic.When the solution is added with NaOH, it will turn pink.Note that NaOH serves as a carbon dioxide neutralizer.The color of the solution will slowly fade after some time, because carbon dioxide is present in the air neutralizing the color effect of the NaOH.
it turns into fushia/purpley colour
if concentration is particularly strong then it became purple
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.

first take 200ml of the sample.then add 1 drop phenolphthalein indicator .titrate against .1 N NaoH
Phenolphtalein is colorless at pH=7.
if concentration is particularly strong then it became purple
it turns into fushia/purpley colour
the solution will turn into pink(which will gradually fade afterwards because carbon dioxide is present in the air that neutralizes the color effect of the hydroxide..
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
Generally tap water is acidic. There is no color changes.
phenolphthalein.
The color is pink with phenolphthalein.
Phenolphthalein is an indicator often used in chemical titrations. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions. The more basic the solution the pinker the solution will become when Phenolphthalein is present.
