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...
A 15 ml aliquot of 1.00 M phosphoric acid is titrated with sodium hydroxide using phenolphthalein as an indicator. If it takes 20.00 ml of sodium hydroxide to reach the endpoint, what is the molarity of the sodium hydroxide? Answer with appropriate significant digits. H3PO4 (aq) + NaOH (aq) --> H2O (l) + Na3PO4
