How do indicators aid titration of acid-base reactions? ?

Indicators are useful when carrying out an acid-base titration because a properly chosen indicator will signal the equivalence point (endpoint) of the reaction. That is, the indicator should change color at the point where the exact amount of one substance has been added to completely neutralize the other (so, both are limiting and neither is in excess.) Titrations are useful because they allow scientists to collect data in a reaction between a solution with a known concentration of solute and a solution with an unknown concentration of solute. This data, then, is used in a stoichiometric calculation to determine the unknown concentration. I hope this helps!
