What happens when water is added to phenolphthalein?
When water is added to phenolphthalein, the color remains the same, which is colorless. Phenolphthalein is typically used as an indicator in titrations with strong acid and strong base where the color change is triggered by changes in pH, not by the addition of water.
What is the color of lime water when phenolphthalein is added into lime water?
The color is pink with phenolphthalein.
What colour appear when lime water plus phenolphthalein?
When lime water (a solution of calcium hydroxide) is mixed with phenolphthalein, the solution turns pink. This occurs because phenolphthalein is a pH indicator that changes color in basic solutions. Lime water is alkaline, so it causes the phenolphthalein to shift from colorless to pink in the presence of a base.
Why will phenolphthalein dissolve in water?
Phenolphthalein dissolves in water because it is a water-soluble compound. The molecule has hydroxyl groups that can form hydrogen bonds with water molecules, allowing it to dissolve readily in water. Additionally, phenolphthalein is often used as a pH indicator in aqueous solutions due to its solubility in water.
Is water heterogeneous or heterogeneous?

How do you make up a solution of phenolphthalein from a whit solid of phenolphthalein?
Dissolve 0.1g of the powder in ethanol and dilute with distilled water upto 100 cm3
