Titration

bromcresol green, methyl red, bromthymol blue, phenol red, neutral red, phenolphthalein, thymolphthalein, alizarin yellow, nitramine, and trinitrobenzoic acid. In this experiment phenolphthalein is the indicator used in the titration process. Discussion of terms Titration is the process of determining the quantity of a substance A which is the acid by adding measured increments of substance B which is the base, with which it reacts (almost always as a standardized solution called the titrant)...

Titration

IUPUI October 12, 2012 Titration of Acids and Bases Introduction According to Arrhenius definition, acid is substance that produces H3O+ ion while base is substance that produces OH- ions. The reaction between acid and base often yields the products of salt and water. The formation of water in this neutralization reaction is caused by the combination of H3O+ and OH- ions. In order to determine the concentration of an unknown acid and base, a method called acid-base titration is used. The end of...
