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 phenolphthalein is added to ammonium hydroxide is the color of the final solution is pink?
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.
When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
Phenolphthalein is pink in a basic environment.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is the indicator to see if it is more acidic or more basic
What happens to the pH of An aqueous solution if a few drops of acid are added to it?
If the solution is not basic then the pH will fall below 7
Why phenolphthalein get colour on basic medium?
In a basic medium phenolphthalein changes color frompink to colorless.
What happens if phenolphthalein was added to salts?
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.
How will Phenolphthalein help you test for unknown substances?
phenolphthalein turns pink when basic solution is added to it but remains colorless in case of neutral and acidic solution
When phenolphthalein is added to ammonium hydroxide is the color of the final solution is pink?
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.
What does pink in phenolphthalein mean?
The solution is basic.
When a drop of phenolphthalein is introduced in barium hydroxide the solution turns what colour?
Phenolphthalein is pink in a basic environment.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is the indicator to see if it is more acidic or more basic
Why we use phenopthline as indicator for determining theconcentration of oh?
Phenolphthalein change the color from pink in basic solutions to colorless in acidic solutions.
What happens to the pH of An aqueous solution if a few drops of acid are added to it?
If the solution is not basic then the pH will fall below 7
Why would a solution of sodium and phenolphthalein and water be fuchsia?
When phenolphthalein comes into contact with a basic solution, it turns pink-ish, or as you see it, fuchsia. When sodium and water react, the result is NaOH. Given that the presence of OH ions is, in essence, what makes a solution basic, it goes without saying that a solution of the three would be pink/fuchsia.
What is the color of phenol red at acidic pH?
Very strong acid solutions that have phenolphthalein added to them turn orange, but in general acidic solutions with phenolphthalein are colorless. If the solution is titrated to slightly basic (pH > 8.2) it will turn pink. Note that in extremely basic solutions (pH > 13) it will revert to colorless again.
Why phenolphthalein get colour on basic medium?
In a basic medium phenolphthalein changes color frompink to colorless.
When the acidic solution is added to the basic solution what happens to the pH does it increase decrease or stays the same?
It depends on the original pH of both solutions.
