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.

What color does NaoH turn when phenolphthalein?

NaOH turns pink when phenolphthalein is added.


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.


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.


Can you use indicator other than phenolphthalein in the titration of NaOH?

Yes, you can use indicators such as bromothymol blue or methyl orange in the titration of NaOH. These indicators change color at different pH ranges and can be used based on the specific pH endpoint needed for the titration.


Why methyl orange is used instead of phenolphthalein in hcl and naoh titration?

This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used


What is the equation of sodium hydroxide with phenolphthalein with hydrochloric acid?

The equation for the reaction between sodium hydroxide (NaOH) and hydrochloric acid (HCl) using phenolphthalein indicator is: NaOH + HCl → NaCl + H2O Phenolphthalein is a pH indicator that turns pink in basic solutions and colorless in acidic solutions.


Which indicator is used in titration of naoh and h2so4?

Phenolphthalein is commonly used as an indicator in the titration of NaOH and H2SO4. It changes color from colorless to pink as the solution reaches a specific pH range, signaling the endpoint of the titration.


Which indicator would you use in the titration sulphuric acid with naoh?

In the titration of sulfuric acid with sodium hydroxide (NaOH), a pH indicator suitable for a strong acid-strong base titration, such as phenolphthalein, can be used. Phenolphthalein changes color at around pH 8.2-10, which is suitable for detecting the endpoint of the neutralization reaction between sulfuric acid and sodium hydroxide.


What indicator can you choose for the titration of oxalic acid with sodium hydroxide?

Phenolphthalein is a suitable indicator for the titration of oxalic acid with sodium hydroxide. It changes color from colorless to pink at the endpoint of the titration when the acid has been completely neutralized.


Why you use phenolphthalein as a indicator in titration of NaOH with HCL?

Phenolphthalein is normally used for this reaction as it accurately displays the end point of the reaction, turning colorless as soon as it reaches the end point of the reaction. If carrying out this reaction, be careful, as the change is usually quite sudden. The color exhibited should be pink (or "fuchsia") at the beginning of the reaction. As it progresses, it should become lighter in color, until it becomes colorless suddenly.
