Actually it is both at the same time:
weakly acidic in fully protonated (compound formula H+PPT), no color, pH < 8
and
weakly base when deprotonated (PPT), with blue-purple color at pH > 8 - 10

What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is the indicator to see if it is more acidic or more basic
What happens when phenolphthalein mixes with saliva?
Phenolphthalein is a pH indicator that turns pink in basic solutions, and colorless in acidic solutions. Normal pH of saliva ranges between 6.2 (acidic) and 7.4 (basic), with 7 being neutral pH. So, the answer is, "it depends." Is the saliva acidic, or basic?
When phenolphthalein is added to ammonium hydroxide is the color of the final solution is pink?
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.
What is the colour of phenolphthalein indicators in acidic and basic properties?
In acid conditions it is colorless and in basic conditions it is pink and then bright red
What is indicator which has no color with the acidic medium?
Phenolphthalein and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.

Why we use phenopthline as indicator for determining theconcentration of oh?
Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.

How will Phenolphthalein help you test for unknown substances?
phenolphthalein turns pink when basic solution is added to it but remains colorless in case of neutral and acidic solution
What is the colour of phenolphthalein indicators in acidic and basic properties?
In acid conditions it is colorless and in basic conditions it is pink and then bright red
What does phenolphthalein mean in science?
Phenolphthalein is a chemical compound with the formula C20H14O4. It is coloured, and the colour changes in relation to the acidity of it environment. It turns colorless in acidic solutions and pink in basic solutions.

Phenolphthalein and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.
When does phenolphthalein turn pink?
Phenolphthalein in acidic titrations,turns colorless and pink in basic solutions.
What is the color of phenol red at acidic pH?
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
What color does phenolphthalein go in acid?
Orange in acidColourless in neutral solutionsPink/ purple in alkalisactually you are wrong the correct answer for this is....clear acidic solutionspink in basic solutionsand a pinkish-clear colour in neutral solutionsyou shouldn't always believe what you read i have this confirmed from my textbook which is by far a better source.
Why phenolphthalein get colour on basic medium?
In a basic medium phenolphthalein changes color frompink to colorless.
