Polyprotic acids pogil
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 …
31. Sometimes the chemical formula of an acid can be misleading. Phosphoric acid (H 3 PO 4) is a triprotic acid, but phosphorous acid (H 3 PO 3) is a diprotic acid, and hypophosphorous acid (H 3 PO 2) is a monoprotic acid. a. Draw Lewis dot-diagrams for each of these three acids. All of the structures include a double bonded oxygen.
Figure 15.6.3: The Titration of (a) a Weak Acid with a Strong Base and (b) a Weak Base with a Strong Acid. (a) As 0.200 M NaOH is slowly added to 50.0 mL of 0.100 M acetic acid, the pH increases slowly at first, then increases rapidly as the equivalence point is approached, and then again increases more slowly. 2 ™ Activities for AP* Chemistry POGIL 4. Examine the titration curve for the diprotic acid. How many equivalence points are there? Place an X on each equivalence point. Read This! When polyprotic acids react with hydroxide ions (or any other base) in solution, hydrogen ions are do-nated one at a time.Calculate the pH of a 4.00 mol L−1 4.00 m o l L − 1 solution of citric acid. pKa1 = 3.09 pKa2 = 4.75 pKa3 = 6.40 p K a 1 = 3.09 p K a 2 = 4.75 p K a 3 = 6.40. Usually for polyprotic acids, we can assume that the second, third and other dissociations of HX+ H X + ions are negligible when compared to the first dissociation.This stepwise ionization process occurs for all polyprotic acids. Carbonic acid, H 2CO 3, is an example of a weak diprotic acid. The first ionization of carbonic acid yields hydronium ions and bicarbonate ions in small amounts.

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:Polyprotic Acids Many acids contain two or more ionizable hydrogens. There are two in carbonic acid, H 2 CO 3, and three in phosphoric acid, H 3 PO 4. For any such multiple hydrogen acid, the first hydrogen is most easily removed, and the last hydrogen is removed with the greatest difficulty. These acids are called polyprotic (many protons) acids.with Ka2 = 1.2 ×10−2 K a 2 = 1.2 × 10 − 2. This stepwise ioniza tion process occurs for all polyprotic acids.
