A more challenging problem is to find the pH of a solution that contains a polyprotic weak acid or one of its conjugate species. As an example, consider the amino acid alanine, whose structure is shown in Figure 6.7.1 . The ladder diagram in Figure 6.7.2 shows alanine’s three acid–base forms and their respective areas of predominance.

The volume begins with an overview of POGIL and a discussion of the science education reform context in which it was developed. Next, cognitive models that serve as the basis for POGIL are presented, including Johnstone's Information Processing Model and a novel extension of it. Adoption, facilitation and implementation of POGIL are addressed next.These molecules are known as polyprotic acids and bases and include: diprotic acids and bases Ba(OH)2 2SO4 +H 3NCHCO2H 2CO3 HOOCCH2COOH triprotic acids H3PO4 tetraprotic acids (HOOCCH2)2-NCH2CH2N-(HOOCCH2)2 Obviously polyprotic systems are more problems to deal with.5.

For a triprotic acid, the other two equivalence points should correspond to 1/3 and 2/3 of the volume of the base required to reach the final one and thus one can still determine ...pH = -log 0.211 = 0.68. To summarize, when calculating the pH of a polyprotic acid, in most cases, the second ionization step is ignored, and we follow the same steps as for calculating the pH of a weak monoprotic acid: 1) Write the equation for the dissociation of the acid. 2) Assign x mol/l for the concentration of the acid that dissociates.The other is to note that citric acid has a significant buffer region that stretches from a pH of about 2.5 to 5.5. Citric acid is commonly used as a buffer for this pH region. It is also worth examining what would be observed for a similar plot of a different triprotic acid. The data in Table 5 is for an identical titration of phosphoric acid.

The differences in the acid ionization constants for the successive ionizations of the protons in a polyprotic acid usually vary by roughly five orders of magnitude. As long as the difference between the successive values of K a of the acid is greater than about a factor of 20, it is appropriate to break down the calculations of the concentrations of the ions in …9.0 and 11.0.
