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?

Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.


Why there is no colour change when phenolphthalein is added to the oxalic acid?

Oxalic acid is a weak acid and phenolphthalein is a pH indicator that changes color in the pH range of 8.2 to 10. Oxalic acid solutions typically have a pH below the range where phenolphthalein changes color, so there is no visible change when phenolphthalein is added to oxalic acid.


What happens if phenolphthalein solution is added in hydrochloric acid?

If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.


What happens if sulfuric acid is added in phenolphthalein?

Sulfuric acid is a strong mineral acid that can react with phenolphthalein, which is a pH indicator. In the presence of sulfuric acid, phenolphthalein can turn colorless due to the acidic conditions. This color change occurs because the sulfuric acid donates protons to the phenolphthalein molecule, changing its structure and causing it to lose its pink color.


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.

If phenolphthalein is added to HBr?

If phenolphthalein is added to HBr (hydrobromic acid), which is a strong acid, the phenolphthalein indicator will remain colorless because it only changes color in the presence of a base. Since HBr is an acid, it will not cause the indicator to change color.

What happens when you mix HCl and phenolphthalein?

When you mix HCl (hydrochloric acid) and phenolphthalein, the phenolphthalein will turn colorless because the strong acid protonates it, resulting in the loss of its pink color. This change in color indicates the presence of an acidic solution.


Why is phenolphthalein colorless in hydrochloric acid?

Phenolphthalein is colorless in acidic conditions, such as hydrochloric acid, because it undergoes protonation, forming a colorless form of the molecule. This protonation reaction alters the structure of phenolphthalein, preventing it from exhibiting a color change.


What happen when phenopthelein is added to acid?

Phenolphthalein is colorless in acidic solutions and will remain colorless when added to an acid. This is because phenolphthalein changes color at a pH of around 8.2 to 10, indicating alkalinity.


Why does hydrochloric acid change phenolphthalein purple to colorless?

Hydrochloric acid is a strong acid that neutralizes the alkaline properties of phenolphthalein, turning it colorless. This reaction occurs because the acid donates hydrogen ions, causing a shift in the pH balance and resulting in the loss of the pink or purple color in phenolphthalein.


What colour in sulfuric acid is phenolphthalein?

Phenolphthalein is colorless in sulfuric acid.


What is the reaction of hydrochloric acid and phenolphthalein?

Hydrochloric acid (HCl) is a strong acid that will react with phenolphthalein, a pH indicator, causing it to turn colorless in acidic conditions. This reaction occurs due to the change in pH of the solution, which shifts the equilibrium of the phenolphthalein molecule leading to its color change.
