Answer:

To signal a stoichiometric endpoint...........

Explanation:

Classically, such indicators were used in an acid-base titration. The precipitous rise in pH during a titration means that a selection of indicators can be used, and #pK_a("indicator")# can be around #4-10#; as seen in a titration of acid with base, the endpoint occurs within #0.01*mL# (approx. 1 drop) of added titrant.......
