Phenolphthalein solution is used as an indicator of acids and bases. If added to an ammonia-based solution of window cleaner we would expect the solution to turn?
As ammonia solution is alkaline, about pH 11 - 12, the phenolphthalein will turn pink.
What happens when you mix HCl and phenolphthalein?
After a pH=10 the color of phenophthalein is fuchsia.
What color does NaoH turn when phenolphthalein?
Pink
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 color does phenolphthalein turn in base?
if concentration is particularly strong then it became purple

What would happen if I placed a Vial of phenolphthalein into a jar with ammonia?
Nothing will happen... but when you put a drop of the vial in the phenolphthalein, the phenolphthalein will turn into pink... It was just an observation that I saw in our experiment this afternoon

What color does phenolphthalein turn when dipped in water?
Phenolphtalein is colorless at pH=7.
What color does phenolphthalein turn in base?
if concentration is particularly strong then it became purple
What color would tap water turn with phenolphthalein?
Generally tap water is acidic. There is no color changes.
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 colour does hydrochloric acid turn phenolphthalein?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
Dipping a piece of red litmus paper into household ammonia will cause the litmus to turn what color?
The color turn on blue.
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).
