<!--pH at the end-point depends mainly on the strength of the acid, p''K''<sub>a</sub>.
Line 64 ⟶ 70:
* The pH rises more steeply at the end-point as the acid concentration increases.
When a weak acid is titrated with a strong base the end-point occurs at pH greater than 7. Therefore, the most suitable [[PH indicator|indicator]] to use is one, like [[phenolphthalein]], that changes color at high pH.<ref>{{Cite book|title=Chemical Principles|year=2009|publisher=Houghton Mifflin Company|location=New York|pages=319–324|author=Steven S.
