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...

DETERMINATION OF A CHEMICAL FORMUL 4. If some of the calcium metal remains unreacted when you start the titration, the calcium will react with hydrochloric acid to produce hydrogen gas. CaloH)₂ + 2HCl cacla & H2O Ca (s) + 2 HCl(aq) +CaCl2 (aq) + H2 (8) Would this cause error in the titration? If so, would more or less HCl be required? How would this affect the molecular formula for calcium hydroxide? bicarbonate that must be used to neutralize the...
