HBrO(pKa is 8.70) ( is 8.70) alizarin yellow R phenolphthalein or thymolphthalein alizarin or bromthymol blue bromocresol green or methyl red o-cresolphthalein or phenolphthalein
Homework Answers
Here, HBrO is a weak acid, hence one has to use Phenolphthalein as an indicator in the titration of a HBrO with NaOH or KOH.
Explanation: Phenolphthalein is the best indicator in the titration of a weak acid with a strong base.
Add Answer to:
HBrO(pKa is 8.70) ( is 8.70) alizarin yellow R phenolphthalein
or thymolphthalein alizarin or bromthymol blue...
