Why does NaOH turns pink when phenolphthalein indicator is added?

Due to the increase of the pressure found within the flame of the bunsen burner, the pressure creates a vacuum thus sucking the phenollphthalein up and turning the solution to the color of the akaline solution.

phenolphthalein is an indicator designed to identify the pH of bases.

What chemical reaction between the phenolphthalein and NaOH?
Phenolphthalein turns pink as NaOH is a strong alkali
Color of phenolphthalein plus NaOH?
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.
Best indicator for lactic acid when titrated against standard NaOH?
phenolphthalein.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
Is sodium hydroxide a base or acid how will you justify?
Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.

Adding an acid base indicator to a sodium hydroxide solution can verify that it is an alkaline solution. For example, phenolphthalein turns pink in an NaOH solution.
What indicator can you choose for the titration of oxalic acid with sodium hydroxide?
Phenolphthalein, because NaOH is a strong base.
In HCl and NaOH titration which indicator is used?
Phenolphthalein indicates red for acids and blue for bases.
What is the colour change in the titration of NaOH and C2H2O4 if using phenolphthalein as an indicator?
Adding NaOH-sol'n to oxalic acid, C2H2O4, the colour (from colorless) has to become purple-blue at pH 8 to 10.
What color does NaoH turn when phenolphthalein?
Pink
What happens if you mix bromphenol blue and NaOH?
Bromophenol blue pH indicator changes from yellow at pH 3.0 to blue at pH 4.6; it turns blue even in neutral water (pH=7) so when NaOH is added nothing really changes: blue = blue
What tool can test the acidity of a liquid?
first take 200ml of the sample.then add 1 drop phenolphthalein indicator .titrate against .1 N NaoH
Why would a solution of sodium and phenolphthalein and water be fuchsia?
When phenolphthalein comes into contact with a basic solution, it turns pink-ish, or as you see it, fuchsia. When sodium and water react, the result is NaOH. Given that the presence of OH ions is, in essence, what makes a solution basic, it goes without saying that a solution of the three would be pink/fuchsia.
