Draw the titration curve for the titration of 20 mL of a 0.12 M solution of glutamate (carboxylic acid pKa = 2.19, amino pKa = 9.67, you need to know the pKa for the R group) with 0.10 M sodium hydroxide. Clearly label the axes of your graph (pH vs mL of NaOH added.) Be sure to include pH values and volumes for the following: Start of the titration (no sodium hydroxide added), the pH at the volume that is...

To learn about titration types
and how to calculate pH at different points of titration. In an
acid-base titration, a titrant (solution of a base or acid) is
added slowly to an analyte (solution of an acid or base). The
titration is often monitored using a pH meter. A plot of pH as a
function of the volume of titrant added is called a pH titration
curve. Prior to the titration, the pH is determined by the
concentration of the...
