What happens when sodium hydroxide is added dropwise to solution containg phenolphthalein?
At a particular point, the color of the indicator would change from colorless to pink (purple).
Why phenolphthalein is chosen as the suitable indicator for sodium hydroxide?
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.
What color does Phenolphthalein possess in the presence of excess hydroxide ions?
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.
What is the chemical reaction of phenolphthalein and sodium hydroxide?
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..
What is the color produced when you add the phenolphthalien to sodium hydroxide solution?
You will get a pink to a pinkish-red solution depending on how concentrated the sodium hydroxide (NaOH) is.

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.
If Phenolphthalein solution is added to an ammonia-based solution of a window cleaner what color would it be?
pink
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.
In an ammonia stock with phenolphthalein solution would the sodium hydroxide tend to decrease the color intensity?
Both are basic, so color is not pricipally changed.
What is the color of lime water when phenolphthalein is added into lime water?
The color is pink with phenolphthalein.
Why there is no colour change when phenolphthalein is added to the oxalic acid?
In a weak acid solution phenophthalein has the "lactone" form which hasn't color.
What is the color of phenolphthalein in baking powder?
The solution is colorless.
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).
What color does Phenolphthalein possess in the presence of excess hydroxide ions?
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.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
