Orange in acid
Colourless in neutral solutions
Pink/ purple in alkalis
actually you are wrong the correct answer for this is....
clear acidic solutions
pink in basic solutions
and a pinkish-clear colour in neutral solutions
you shouldn't always believe what you read i have this confirmed from my textbook which is by far a better source.

Phenolphthalein change color when mixed with hydrochloric acid?
No, phenolphthalein remains colourless in the presence of an acid.
What colour does hydrochloric acid turn phenolphthalein?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
Why there is no colour change when phenolphthalein is added to the oxalic acid?
In a weak acid solution phenophthalein has the "lactone" form which hasn't color.
What does Phenolphthalein indicate?
Phenolphthalein indicates the presence of an acid or base within substance. When there is a base present the phenolphthalein will create a pink to fuchsia color. When an acid is present the phenolphthalein will create a colorless to orange color.
Why is phenolphthalein colorless in hydrochloric acid?
phenolphthalein only turns pink in a solution that is a base. Hydrochloric acid is obviously an acid.

What colour does hydrochloric acid turn phenolphthalein?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
How does the color change when a strong acid is added an alkali to neutralise?
The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless
What does Phenolphthalein indicate?
Phenolphthalein indicates the presence of an acid or base within substance. When there is a base present the phenolphthalein will create a pink to fuchsia color. When an acid is present the phenolphthalein will create a colorless to orange color.

In a weak acid solution phenophthalein has the "lactone" form which hasn't color.
What happens if phenolphthalein was added to salts?
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.
Why is phenolphthalein colorless in hydrochloric acid?
phenolphthalein only turns pink in a solution that is a base. Hydrochloric acid is obviously an acid.
Substance that is of one color in an acid solution and of another color in a basic solution is a what?
An acid-base indicator. Some examples are phenolphthalein and methyl orange.
What happens when you mix HCl and phenolphthalein?
After a pH=10 the color of phenophthalein is fuchsia.
What is the color of lime water when phenolphthalein is added into lime water?
The color is pink with phenolphthalein.
What color is phenolphthalen in an acid?
Phenolphthalein is an organic compound (C20H14O4) used as an acid-base indicator. The compound is colorless in acidic solution and pinkish in basic
Why does hydrochloric acid change phenolphthalein purple to colorless?
we know that hcl is an acid and acids change purple phenolphthalein to colourless. So HCL changes purple phenolphthalein to colourless
