What chemical reaction between the phenolphthalein and NaOH?
Phenolphthalein reacts with NaOH in a neutralization reaction, where the acidic H+ ions in phenolphthalein are replaced by the basic OH- ions from NaOH. This reaction leads to the formation of a pink color indicating the basic nature of the solution.
Color of phenolphthalein plus NaOH?
Phenolphthlalein is something like a pH indicator. When it is added to a liquid and the liquid turns pink, it means that the latter substance is basic.When the solution is added with NaOH, it will turn pink.Note that NaOH serves as a carbon dioxide neutralizer.The color of the solution will slowly fade after some time, because carbon dioxide is present in the air neutralizing the color effect of the NaOH.
Why phenolphthalein used as best indicator against NaOH?
Phenolphthalein is a suitable indicator for NaOH because it changes color sharply from colorless to pink at the pH range of 8.2 to 10.0, which corresponds well to the endpoint of the titration of NaOH with an acid. This sharp color change allows for accurate and precise detection of the equivalence point in the titration process.
Why does NaOH turns pink when phenolphthalein indicator is added?
Due to the increase of the pressure found within the flame of the bunsen burner, the pressure creates a vacuum thus sucking the phenollphthalein up and turning the solution to the color of the akaline solution.
In HCl and NaOH titration which indicator is used?
Phenolphthalein is commonly used as an indicator in the titration of hydrochloric acid (HCl) with sodium hydroxide (NaOH). Phenolphthalein changes color from colorless to pink at the endpoint of the titration when all the acid has been neutralized by the base.

What color does ammonia turn when phenolphthalein is added?
Ammonia will turn pink when phenolphthalein is added, indicating that the solution is basic.
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.
Do bases turn phenolphthalein clear?
No, bases turn phenolphthalein pink or purple in color. Phenolphthalein is colorless in acidic solutions and turns pink in basic solutions with a pH higher than around 8.2.
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 is the chemical reaction of phenolphthalein and sodium hydroxide?
Phenolphthalein reacts with sodium hydroxide to form a pink color, indicating the presence of a base. The chemical reaction involves the deprotonation of phenolphthalein by hydroxide ions to form an ionized molecule with a pink hue.
What color do bases turn phenolphtalein?
Phenopthalene turned into pink.pH should be above 10.
Phenolphthalein change color when mixed with hydrochloric acid?
Phenolphthalein is a pH indicator that changes color in response to a change in pH. When mixed with hydrochloric acid (a strong acid), phenolphthalein will turn colorless due to the decrease in pH, indicating an acidic solution.
