What Is an End Point in Titration
Remember that what we calculate is not the pH at the end point - but the theoretical pH at the equivalence point. The equivalence point or end point is the exact point where all the analyte in solution has reacted. Titration Easy Science Easy Science Ap Chemistry Biology Notes Consider a solution initially containing 040 mol fluoride anion and 030 mol of hydrogen fluoride HF. . Hence phenolphthalein is a suitable indicator as its pH range is 8-98. However methyl orange is not suitable as its pH range. Reasons of this difference are discussed in details in the end point detection and acid-base titration end point detection sections. In some cases excess of the titrant must be used as it is titrant color that signals end point. The isoelectric point isoelectric pH. Point halfway point Figure 2. Since the equivalence point of many titrations do not result in observable changes end point indicators are added t...
