Unformatted text preview: rom Experiment 4C, a theoretical expectation of three equivalence points does not always result in an experimental observation of those points. Solvent effects: The pH of the solvent can affect whether or not a species is protonated. The presence of excess hydronium ions in an acidic solution will shift the equilibrium of a weak acid to the left, leaving the species in the protonated form: HA (aq) + H2O (ℓ) ! A- (aq) + H3O+ (aq) In basic solutions, the lack of hydronium ion pushes the equilibrium to the right, leaving the deprotonated version in solution. Data analysis: Print out the experimental titration curves of the amino acids derived from dietary supplements from Canvas. You may work in teams of 2 to complete this part of the assignment. You may not, however, use outside sources to...
