WebJul 26, 2014 · Below is a typical curve for the titration of glycine with NaOH. Although we often write glycine as NH₂COOH, it is really a zwitterion, + NH3CH2COO⁻. The fully protonated form of glycine is + NH3CH2COOH. Step 1 is the loss of H+ from the carboxyl group. Step 2 is the loss of H+ from the less acidic NH+ 3 group. WebØ As the NaOH is gradually added, the OH¯ ions present in it will combine with the free H⁺ ions in the medium to form H 2 O.. Ø As the titration proceeds, the free H⁺ ions are removed by the addition of OH¯, more and more acetic acid molecules will dissociate to satisfy its own equilibrium constant.. Ø At the mid-point of titration, one half of the original acetic …
