Trend 3: For polyprotic oxoacids the acidity decreases as each successive proton is removed. Oxoacids with multiple O-H bonds are called polyprotic since they can donate more than one hydrogen ion. In this case hydrogen ions are removed in successive ionization reactions. Examples include phosphoric and carbonic acid:

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.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.

Thankfully, the process is essentially the same as finding the pH of a polyprotic acid except in this case we deal with the concentration of OH - instead of H 3 O +. Example 2: Finding the pH of a polyprotic base.

The pKb of ammonia is 4.75 at 25°C. Answer. As shown in part (b) in Figure 17.4.3, the titration curve for NH3, a weak base, is the reverse of the titration curve for acetic acid. In particular, the pH at the equivalence point in the titration of a weak base is less than 7.00 because the titration produces an acid.-POGIL: Strength of Acids -Finish POGIL -Watch: Weak Acid and Base Calculations -Problem Set: Acid/Base Definitions & pH Answer Key-EXTRA PRACTICE: Recognizing Acids and Bases pH Calculations Fri 11/3 -Notes: Relative Strength of Acids and Bases Powerpoint: slides 15-22 -Notes: Weak Acid/Base Calculations™POGIL Activities for AP* Chemistry Equilibrium Systems Reaction Quotient . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .181 . Sometimes the chemical formula of an acid can be misleading.
