in the presence of a base
in the presence of an acid
when it is in a neutral solution
when it is reacting with a metal
Basic/alkaline solutions turn phenolphthalein pink.
Alkalies above pH 8 turn phenolphthalein pink.
No, acids do
A pink color in a solution with phenolphthalein indicates that the solution is basic. In acid phenolphthalein solutions, the solution will turn colorless.
pinkPink colour in alkali.
phenolphthalein is a weak acid, when reacting with strong alkali it turns pink
The phenolphthalein molecule is colorless but the phenolphthalein ion is pink. When a base is present in a solution containing phenolphthalein, the molecule to ions equilibrium shifts to create more (pink) ions than (colorless) molecules.
Phenolphthalein turns pink in the presence of a base or any solution with a ph over 7.
it will turn pink. phenophathaline turns pink in alkaline ph
base on theory, it should turn pink
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
No, Coke would have to have a PH of more than 10 to turn pink. Coke only has a PH of 3
As ammonia solution is alkaline, about pH 11 - 12, the phenolphthalein will turn pink.
Phenolphthalein turns pink in acids
it is colorless but it will turn pink to indicate that the end-point has been reached
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.
Phenolphthalein is colorless in acid and pink ins a basic solution.
The color is pink with phenolphthalein.
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.
Phenolphthalein in acidic titrations,turns colorless and pink in basic solutions.
