What color does NaoH turn when phenolphthalein?
Pink
Do bases turn phenolphthalein pink?
No, acids do
Why does Phenolphthalein turn pink in potassium hydroxide solution?
phenolphthalein is a weak acid, when reacting with strong alkali it turns 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.
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 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
Will phenolphthalein turn pink in coca-cola?
No, Coke would have to have a PH of more than 10 to turn pink. Coke only has a PH of 3
Can phenolpthalein solution be used to prove that toothpaste is a base?
Phenolphthalein changes from colorless to pink in the range of pH 8.2 - 10. If toothpaste has a pH that is below this range, phenolphthalein will not indicate the basicity. if the pH is higher, which I believe it is in most (some) toothpastes, then phenolphthalein can be used, because it will turn from colorless to pink.
What happens when you mix HCl and phenolphthalein?
After a pH=10 the color of phenophthalein is fuchsia.
