Phenolphthalein would not be an appropriate indicator to use to determine the Ka1 of phosphoric acid Why What indicator would be appropriate?

Because Phenolphthalein changes color from a pH of 8-10. Orange IV would be a better indicator since it changes color around a pH of 2-3.

Why is phenolphthalein used in the titration experiment?
it is used as an acid-base indicator
Does phenolphthalein indicator remain clear in a acid?
Fdf
Is the universal indicator or phenolphthalein is more accurate?
THe universal indicator is more accurate as it can detect different ranges in the pH, whereas phenolphthalein only changes at a ph of 8.0
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 is phenolphthalein an appropriate indicator for acid base titrations?
Razor Sharp end point which is between pH 8 and 9 so almost perfectly neutral too.
What is the colour of zinc ions mixed with ammonia in phenolphthalein indicator?
The phenolphthalein indicator is pink in basic solutions.
Why is phenolphthalein indicator used?
Phenolphthalein is used as an indicator because the color of the solution is changed according to pH.
Why is phenolphthalein used in the titration experiment?
it is used as an acid-base indicator
Why you are adding phenolphthalein as a indicator?
One would add phenolphthalein as an indicator for bases with a pH of 8.2 to 10.0 If the phenolphthalein changes color from colorless to pink or red, a base with a pH between the aforementioned pH values is present.

Why you use phenolphthalein in titration?
it acts as acid base indicator
Why phenolphthalein used in titration?
it acts as acid base indicator
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.
How much phenolphthalein indicator should be used?
A few drops of any indicator is generally enough to get a reading.
