In a basic medium phenolphthalein changes color frompink to colorless.
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.
Pink. Calcium hydroxide turns phenolphthalein pink when it is in a basic solution.
Phenolphthalein and other indicators which themselves are weak acid show a colour change in basic medium (between pH value 7.1 to 14) so in acids they remain unchanged.
In acid conditions it is colorless and in basic conditions it is pink and then bright red
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.

Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
Phenolphthalein only gives colour to bases with a pH above approximately 8.2-10. Then it gives a pink colour. As HCL is a strong acid it becomes colourless.
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
The color of phenolphthalein after the addition of dilute HCl is colorless. Phenolphthalein is typically pink in basic solutions but turns colorless in acidic conditions due to the change in pH.
The solution turns pink when a drop of phenolphthalein is introduced in barium hydroxide. Phenolphthalein is a pH indicator that changes color in the presence of alkaline solutions, indicating the basic nature of barium hydroxide.
Phenolphthalein is colorless in tap water, as tap water is typically neutral to slightly acidic. It only turns pink in basic solutions with a pH above 8.2.
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.
