Phenolphtalein is colorless at pH=7.
dark green
If it is pure water, it doesn't change.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
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.
When ammonia is dissolved in water and phenolphthalein is added, the solution turns pink. This occurs because ammonia is a weak base, and the phenolphthalein indicator changes color in basic conditions. The pink color indicates a pH greater than 8.2, which is typical for ammonia solutions.
It would turn Green
NaOH turns pink when phenolphthalein is added.
Generally tap water is acidic. There is no color changes.
dark green
If it is pure water, it doesn't change.
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
Assuming the water is pure... there will be no change - since pure water has a pH of 7.
Phenolphthalein will turn pink or magenta in color when added to a basic solution containing hydroxide ions.
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.

Phenolphthalein is a pH indicator and cannot be used to turn water into wine. Wine is made through the process of fermentation using grapes or other fruits, yeast, and time. Phenolphthalein changes color in response to a change in pH, typically from colorless to pink or red in the presence of a base.
