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.
What color does phenolphthalein turn in base?
if concentration is particularly strong then it became purple
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.
What happens when you mix HCl and phenolphthalein?
After a pH=10 the color of phenophthalein is fuchsia.
Is NaCl a base acid or neither?
It is a neutral. Try it with litmus paper and no color change will occur.
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.

How does phenolphthalein work?
Phenolphthalein is an indicator that undergoes a colour change from colourless to pink that begins at a pH of 8.0. So in the titration your performing the phenolphthalein will start to change colour at the point when the moles of acid equal the moles of base. Although this colour change occurs at a pH of 8.0 and not at a pH of 7.0 phenolphthalein is commonly used because of the distinctive colour change that occurs. Phenolphthalein is colourless in acids and pink/purple in base. It also turns orange in very strong acids.

Phenolphthalein goes what colour in a base?
Phenolphthalein turns pink in a base and turns colourless in a base
Why you are adding phenolphthalein as a indicator?
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.
What happens when you mix HCl and phenolphthalein?
After a pH=10 the color of phenophthalein is fuchsia.
Is NaCl a base acid or neither?
It is a neutral. Try it with litmus paper and no color change will occur.
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
How does the SN1 reaction in this experiment cause the acid-base indicator phenolphthalein to change color?
The displacement of chloride or bromide by and iodine ion in an acetone based solution will cause this type of reaction to happen in this experiment.
What will happen when phenolphthalein paper is used to test a base?
It will change its colour from white to red on increasing the pH(for bases)
