What colour does phenolphthalein change to when it reacts with and alkaline solution?
Phenolphthalein changes from colorless to pink when it reacts with an alkaline solution.
Why phenolphthalein get colour on basic medium?
Phenolphthalein is colorless in acidic solutions but turns pink or purple in basic solutions because the hydroxide ions in the basic medium react with phenolphthalein to form a pink-colored compound. This color change is due to a shift in the chemical structure of phenolphthalein when exposed to a basic environment.
What color change the occur when phenolphthalein is put into the base?
Phenolphthalein changes from colorless to pink in a basic solution. This color change occurs because phenolphthalein is a pH indicator that is clear in acidic solutions and pink in basic solutions with a pH above 8.2.
What color does phenolphthalein turn in base?
if concentration is particularly strong then it became purple
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.

What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.

Do bases turn phenolphthalein clear?
No, bases turn phenolphthalein pink or purple in color. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions with a pH higher than around 8.2.
What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
Which idicator is red in acid and purple in an alkali?
The indicator that turns red in acid and purple in alkali is phenolphthalein. In acidic solutions, phenolphthalein appears colorless or red, depending on concentration, while in alkaline solutions, it turns purple. This property makes it useful for determining pH levels in various chemical applications.
When phenolphthalein is added to a basic solution what happens?
That really depends on the strength of the acid, the antacid, and how much of each are present in a mixture. Phenolphthalein is a pink in the presence of higher strength bases (pH > 8.2), orange in the presence of very strong acids (pH < 0), and colorless between pH 0 and 8.2, as well as above 12. If your acid and antacid is combined in a single mixture, the color will depend on the ratio of acid and antacid, taking into account the strength of both the acid and the antacid. If you have significantly more antacid than acid, chances are that it will be pink (unless you're using a strong base like sodium hydroxide for your antacid, at which point it will be colorless), while if you have more acid than antacid, it'll be colorless (unless your acid is a superacid such as fluoroantimonic acid, which there's no reason why you would be using it).
Is there a reaction between the ammonium hydroxide inside a plastic bag when immersed in a water with phenolphthalein?
If the phenolphthalein solution turns pink, that means that the plastic bag is permeable to ammonium hydroxide. If it remains colorless, then the plastic bag is not permeable to ammonium hydroxide. If the contents of the plastic bag turn pink, then the plastic bag is permeable to phenolphthalein. If everything remains colorless, then the bag is impermeable to both ammonium hydroxide and phenolphthalein.
What is the colour change in the titration of NaOH and C2H2O4 if using phenolphthalein as an indicator?
In the titration of NaOH and C2H2O4 using phenolphthalein, the colour change will occur at the endpoint when the solution transitions from pink to colourless. Phenolphthalein is pink in basic solutions and colourless in acidic solutions, so once all the oxalic acid is neutralized by the sodium hydroxide, the solution will turn colourless.
