Phenolphthalein turns pink in a basic solution.
Phenolphthalein turns pink in a basic solution.
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.
Phenolphthalein would turn pink in a borax solution, indicating the solution is basic. Borax acts as a weak base in solution and would cause phenolphthalein to change color due to its alkaline nature.
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.
If phenolphthalein solution is added to hydrochloric acid, it will remain colorless since the pH of hydrochloric acid is too low for phenolphthalein to change color. Phenolphthalein typically turns pink in a basic solution but does not show a color change in acidic conditions.
Phenolphthalein turns pink in a basic solution.
If phenolphthalein is added to a solution of salts, it will not undergo any specific reaction. Phenolphthalein is used as an indicator in acid-base titrations, where it changes color depending on the pH of the solution. Since salts do not have acidic or basic properties, phenolphthalein will not exhibit any color change.

Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.

Phenolphthalein is a pH indicator that changes color in response to different pH levels. By using phenolphthalein, you can determine if a solution is acidic or basic based on the color change it exhibits. This can help you identify unknown substances by comparing the color change with known pH values of different substances.
Phenolphthalein changes from colorless to pink in a basic solution. This color change occurs because phenolphthalein is a pH indicator that is clear in acidic solutions and pink in basic solutions with a pH above 8.2.
That really depends on the strength of the acid, the antacid, and how much of each are present in a mixture. Phenolphthalein is a pink in the presence of higher strength bases (pH > 8.2), orange in the presence of very strong acids (pH < 0), and colorless between pH 0 and 8.2, as well as above 12. If your acid and antacid is combined in a single mixture, the color will depend on the ratio of acid and antacid, taking into account the strength of both the acid and the antacid. If you have significantly more antacid than acid, chances are that it will be pink (unless you're using a strong base like sodium hydroxide for your antacid, at which point it will be colorless), while if you have more acid than antacid, it'll be colorless (unless your acid is a superacid such as fluoroantimonic acid, which there's no reason why you would be using it).
Phenolphthalein in a solution containing magnesium hydroxide would remain colorless as it does not change color at a basic pH, where magnesium hydroxide is present. Phenolphthalein changes color in acidic solutions, not basic ones.
