Polyprotic acids pogil.

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.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.Figure 5 shows a weak polyprotic acid being titrated with a strong base. Notice how they are two equivalence points – this means that the polyprotic acid we start with must have two acidic hydrogens to start with, like H 2 A (i.e. H 2 CO 3, etc). Figure 5: Titration of a polyprotic acid with a strong base. Key Concepts and SummaryDiprotic acids contain two ionizable hydrogen atoms per molecule; ionization of such acids occurs in two steps. The first ionization always takes place to a greater extent than the second ionization. For example, sulfuric acid, a strong acid, ionizes as follows:

The second ionization is. HSO − 4 (aq) + H 2O(l) ⇌ H 3O + (aq) + SO2 − 4 (aq) with Ka2 = 1.2 × 10 − 2. This stepwise ioniza tion 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. Carbonic acid, H 2CO 3, is an example of a weak diprotic acid.

Diprotic and Triprotic are specific types of polyprotic acid capable of donating two and three protons, respectively. Polyprotic acids have multiple dissociation constants, such as Ka1, Ka2, Ka3 and equivalence points, depending on the number of times dissociation occurs. These acids are called polyprotic (many protons) acids. The multiple acid ionization constants for each acid measure the degree of dissociation of the successive hydrogens. Table 1 gives ionization data for four series of polyprotic acids.
