maroon maroon
At a particular point, the color of the indicator would change from colorless to pink (purple).
Sodium hydroxide is a base. And phenolphthalein is a pH indicator that changes color at around a pH of 8.4, so you can tell when your solution that endpoint.
When excess of hydrogen or hydronium ions are present in the solution , the solution will have pH less than 0. Phenolphthalein possesses dark orange color to the solution having pH less than 0. Hence, phenolphthalein will possess dark orange color in the presence of excess of hydrogen or hydronium ions.
the solution will turn into pink(which will gradually fade afterwards because carbon dioxide is present in the air that neutralizes the color effect of the hydroxide..
You will get a pink to a pinkish-red solution depending on how concentrated the sodium hydroxide (NaOH) is.

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.

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.
Both are basic, so color is not pricipally changed.
The color is pink with phenolphthalein.
In a weak acid solution phenophthalein has the "lactone" form which hasn't color.
The solution is colorless.
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).
When excess of hydrogen or hydronium ions are present in the solution , the solution will have pH less than 0. Phenolphthalein possesses dark orange color to the solution having pH less than 0. Hence, phenolphthalein will possess dark orange color in the presence of excess of hydrogen or hydronium ions.
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
