When you start looking at the pH of chemicals, the numbers can go to the extremes. …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 POGIL Project is grateful for the support of the National Science Foundation, the Department of Education, the Hach Scientific Foundation, Google Education and University Relations Fund of TIDES Foundation, Merle Robbins, Franklin & Marshall College, and the Toyota USA Foundation.Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO 3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:This stepwise ionization process occurs for all polyprotic acids. When we make a solution of a weak diprotic acid, we get a solution that contains a mixture of acids.

Arrange the acids, HX, HY and HZ in order of increasing acid strength. The strongest acid would have the weakest conjugate base. Weaker bases (at equal concentrations) will have lower pH values (they are less basic). The base strengths must be X-< Y-< Z-The conjugate acids will have the reverse trend: HZ < HY < HX 4. Consider, for example, the following three polyprotic acids: H 2CO 3 (carbonic acid) a diprotic acid that has two pK values: pK a1 = 3.60 and pK a2 = 10.25 H 3PO 4 (phosphoric acid) a triprotic acid that has three pK values: pK a1=2.12 , pK a2=7.21 , and pK a3=12.67 (tyrosine) a triprotic acid that has three pK values: pK a1=2.17, pK a2=9.19 ...Chem 112, Exp 5: Determining Ka's Using pH Titration Curves.
