A diprotic acid is able to donate two protons. A triprotic acid is able to donate three protons; A polyprotic acid dissociates (or ionises) in stages, donating one proton in each stage.16 • Acids, Bases and salts . 16.6 – 16.7 Polyprotic Acids and Additional Practice Problems .

For Beaker A and B, fill in the ICE/ICF charts to determine all equilibrium/final concentrations of the9.0 and 11.0. 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. 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.Key Concepts and Summary. An acid that contains more than one ionizable proton is a polyprotic acid. The protons of these acids ionize in steps. 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.About Pogil.

HSO−4 (aq) +H2O(l) ⇌ H3O+(aq) +SO2−4 (aq) (7.16.5) with Ka2 = 1.2 ×10−2. This stepwise ioniza tion process occurs for all polyprotic acids, meaning that one H + is lost at the time. This process contrasts with the ionization of strong bases such as Ca (OH) 2 in which all the OH- ions are lost in a single ...This illustrates an important point about polyprotic acids: the first ionization always takes place to a greater extent than subsequent ionizations. In most cases, polyprotic acids lose their protons one at a time, with K a1 >> K a2 >> K a3 etc. When we make a solution of a weak polyprotic acid, we get a solution that contains a mixture of acids.3.5: Polyprotic Acids. Extend previously introduced equilibrium concepts to acids and bases that may donate or accept more than one proton. We can classify acids by the number of protons per molecule that they can give up in a reaction. Acids such as , , and that contain one ionizable hydrogen atom in each molecule are called monoprotic acids.9.0 and 11.0. Arrange the acids, HX, HY and HZ in order of increasing acid strength.
