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 ...A polyprotic acid H N A is a molecule with N proton-binding sites. Each site is capable of binding 1 proton; the corresponding site-variable has two states: α i = 0 (empty) and 1 (occupied). In total, there are 2 N microstates α (ν) = (α 1, α 2, … α N), which form a statistical ensemble.Equilibria of Polyprotic Acids. Owing to the large number of species involved, exact solutions of problems involving polyprotic acids can become very complicated. Thus for phosphoric acid H 3 PO 4, the three "dissociation" steps yield three conjugate bases: Fortunately, it is usually possible to make simplifying assumptions in most practical ...

However, NH 4+ will lose an electron and act as an acid (NH 4+ is the conjugate acid of NH 3) by the following reaction: (7.8.4) N H 4 ( a q) + + H 2 O ( l) ⇌ N H 3 ( a q) + H 3 O ( a q) +. This reaction produces a hydronium ion, making the solution acidic, lowering the pH below 7.a2 = 6.3 x 10-8 acid HPO 4 2-(aq) ⇌ H+ (aq) + PO 4 3-(aq) K a3 = 4.2 x 10-13 strength Note: (i) K a1 > K a2 > K a3 Always true for polyprotic acids, i.e., each ionization step is more difficult because it is more difficult to remove H+ from a molecule as its negative charge increases. BUT this does not apply for ionic salts of these acids, e ...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.The strong acid sulfuric acid, H 2 SO 4, is a diprotic acid. Its first ionization, represented by the following acid dissociation equation. H 2 SO 4 → H + + HSO 4– Ka ≈ 10 3. In the second ionization, the amphiprotic hydrogen sulfate acts as an acid. HSO 4– → H + + SO 42– Ka = 1.03 × 10 −2.Salts of Polyprotic Acids. Do not be intimidated by the salts of polyprotic acids. Yes they're bigger and "badder" then most other salts, but they can be handled the exact same way as other salts, just with a bit more math. All of the rules from above still apply, e.g., the pH of a salt of polyprotic acid will always be greater than 7.4. Sketch how the Zn2+ (aq)/Cu (s) electrochemical cell in Model 1 may appear in a lab setup. Label the electrodes and solutions. Include a voltmeter in your drawing.

This reaction produces a hydronium ion, making the solution acidic, lowering the pH below 7.K a = K w / K b or K b = K w / K a. The inverse proportional relation between Ka and Kb means the stronger the acid or base, the weaker its conjugate partner. Figure 14.7 illustrates this relation for several conjugate acid-base pairs. Figure 14.7 Relative strengths of several conjugate acid-base pairs are shown.The ammonium ion is the conjugate acid of the base ammonia, NH 3; its acid ionization (or acid hydrolysis) reaction is represented by. NH 4 + ( a q) + H 2 O ( l) ⇌ H 3 O + ( a q) + NH 3 ( a q) K a = K w / K b. Since ammonia is a weak base, Kb is measurable and Ka > 0 (ammonium ion is a weak acid).
