To start the titration experiment you want to span whole pH range So, what we did was we drop the pH to a very low value to do that we used hydrochloric acid So, we added hydrochloric acid to the glycine solution and drop the pH below 2 and then we started our titration experiment So, the titration experiment was done by drop wise addition ofThe titration of glycine has the following major features The titration is initiated with glycine hydrochloride, Cl − (H 3 + NCH 2 COOH), which is the fully protonated form of the amino acid In this form, the molecule contains two acidic functional groups; therefore, two equivalents of base are required to completely titrate 1 mol of glycine hydrochlorideGlycine an overview | ScienceDirect Topics
Titration curves & equivalence point (article) | Khan Academy
Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution At the equivalence point in an acidbase titration, moles of base = moles of acid and the solution only contains salt and water Diagram ofFigure 1563: The Titration of (a) a Weak Acid with a Strong Base and (b) a Weak Base with a Strong Acid (a) As 0200 M NaOH is slowly added to 500 mL of 0100 M acetic acid, the pH increases slowly at first, then increases rapidly as the equivalence point is approached, and then again increases more slowly156: AcidBase Titration Curves Chemistry LibreTexts
