Add an acid.
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.
your unknown solution made methyl red turn yellow. it also made phenolphthalein stay clear. what rang of pH does your unknown solution have?
It should be clear. Phenolphthalein doesn't change color in the presence of an acid, only a base.
Alkalis turn phenolphthalein pink or magenta.
No, ammonia does not turn phenolphthalein pink. Phenolphthalein is a pH indicator that turns pink in basic solutions, but ammonia is a weak base and typically does not have a strong enough pH to turn phenolphthalein pink.
NaOH turns pink when phenolphthalein is added.
The Phenophtalein will remain clear.
No, phenolphthalein is colorless in acidic solutions. It turns pink or red in basic solutions.
Yes, bases turn phenolphthalein pink because phenolphthalein is colorless in acidic solutions but turns pink in basic solutions with a pH around 8.2 to 10.
Fdf
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
No, Coke would have to have a PH of more than 10 to turn pink. Coke only has a PH of 3
