of the titration from the following pulldown list.________
(bromocresol green / methyl red / bromothymol blue / cresol red /
thymol blue / phenolphthalein)
Homework Answers
(1) The pH curve represents the titration of a strong (weak/strong) acid with a strong (weak/strong)base.
Reason: the volume of acid taken 25 mL of 0.1M and volume of base required is also 25 mL of 0.1M to reach the equivalence point. So it is a titration of strong acid vs strong base.
(2) Choose a suitable indicator for the endpoint of the titration from the following pulldown list phenolphthalein (bromocresol green / methyl red / bromothymol blue / cresol red / thymol blue / phenolphthalein).
