Why is phenolphthalein indicator used in the titration of oxalic acid against sodium hydroxide?
Yes. Phenolphthalein can be used as an indicator for the titration of a weak acid (oxalic acid) against strong base (sodium hydroxide).
Why you use phenolphthalein in titration?
it acts as acid base indicator
Why phenolphthalein used in titration?
it acts as acid base indicator
Why is phenolphthalein is used in titration experiment?
it is used as an acid-base indicator
Why is phenolphthalein used in the titration experiment?
it is used as an acid-base indicator
Discussion for acid-base titration experiment?

What is phenolphthalein used in titration labs?
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.
What is the action of sodium hydroxide on the colour of phenolphthalein?
Phenolphthalein is pink in basic solutions.Phenolphthalein is used as an indicator in volumetry - acid-base titration.
What is the purpose of phenolpthalein?
Phenolphtalein is used as indicator for titration in chemistry. Also as a pH indicator: pink in basic solutions and colorless in acidic solutions. Phenolphatelein can be used to check blood in forensic problems or as a component of some inks.
Can you use indicator other than phenolphthalein in the titration of NaOH?
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
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 tools are used during and acid-base titration experiment?
Burette Methyl orange Phenolphthalein Pipette
