What happens when you mix HCl and phenolphthalein?
When you mix HCl (hydrochloric acid) and phenolphthalein, the phenolphthalein will turn colorless because the strong acid protonates it, resulting in the loss of its pink color. This change in color indicates the presence of an acidic solution.
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 color does ammonia turn when phenolphthalein is added?
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
If phenolphthalein is added to a solution and it turns pink what is the pH of the solution?
The pH of the solution is above 8.2. Phenolphthalein changes color from colorless to pink in the pH range of 8.2 to 10.0.
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 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.
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 will be the color of phenolphthalein when added to a solution of hydroxide?
Phenolphthalein will turn pink or magenta in color when added to a basic solution containing hydroxide ions.
What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will gradually turn pink as the pH increases. This color change is due to the phenolphthalein molecule shifting from its colorless form in acidic conditions to its pink form in basic conditions.
What color does ammonia turn when phenolphthalein is added?
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
If phenolphthalein is added to a solution and it turns pink what is the pH of the solution?
The pH of the solution is above 8.2. Phenolphthalein changes color from colorless to pink in the pH range of 8.2 to 10.0.
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 colour would phenolphthalein go if added to borax solution?
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.
What happen when sodium hydroxide is added drop wise to a solution containing phenolphthalein?
When sodium hydroxide is added dropwise to a solution containing phenolphthalein, the solution will initially remain colorless. Once enough sodium hydroxide has been added to make the solution basic, the color will change from colorless to pink or purple, indicating the presence of hydroxide ions. Phenolphthalein is a pH indicator that changes color in the presence of a base.
What would happen if you added phenolphthalein to sodium hydroxide?
Phenolphthalein is a pH indicator that turns pink in basic solutions. When added to sodium hydroxide, which is a strong base, the phenolphthalein will turn pink to indicate that the solution is basic.
When phenolphthalein is added to a basic solution what happens?
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).
