**Chapter 14: Acids & Bases**• Definitions & Properties of Acids & Bases • Water dissociation & pH • Acids • Strong vs Weak Acids • Polyprotic Acids • Bases • Strong vs weak bases • Acid/Base Properties of Salts • Acid/Base Properties of Oxides • Structure & its Effect on Acid/Base Properties**Example 1**Write dissociation reactions for the following acids: HC2H3O2 C2H5NH3+ Fe(H2O)63+ HClO4**Example 2**Find the concentrations of H+, OH-, and Cl– in a solution of 0.30 M HCl. What is the pH of this solution?**Example 3**Find the concentrations of all species present, the pH, and the percent dissociation of a 0.12 M solution of formic acid, HCHO2.**Example 4**Find the pH of a solution that is 1.0 M in hydrocyanic acid and 1.0 M in hydrofluoric acid.**Example 5**Calculate Ka for a 0.055M solution of propionic acid, HC3H5O2 that has a pH of 3.06.**Example 6**Calculate Ka for a 0.109M solution of formic acid, HCHO2 that has a percent ionization of 3.7%.**Example 7**Calculate the concentrations of H+ and CO32- in a 5.45 x 10-4 M solution of carbonic acid.**Example 8**H2SeO4 is a strong acid with a Ka2 of 1.2 x 10-2. • Find the pH of a 0.150 M solution of H2SeO4 if the second H+ is ignored. • Find the pH of a 0.150 M solution of H2SeO4 if the second H+ is included.**Example 9**Find the concentrations of H+ and OH- in a solution of 0.30 M KOH. Find the pH of this solution.**Example 10**Find [OH-] and the pH of a 0.15 M solution of hydroxylamine, NH2OH. Kb = 1.1 x 10-8**Example 11**The pH of a 0.63M solution of methylamine is 12.22 at 25°C. What is Kb for methylamine at this temperature?**Example 12**Calculate Kb for the cyanide ion.**Example 13**Find Kb for the sulfate ion.**Example 14**Find Ka for the ammonium ion.**Example 15**Predict whether each of the following solutions is acidic, basic, or neutral. • HONH3Cl (aq) • K3PO4 (aq) • Cu(NO3)2 (aq) • CH3NH3OCl (aq)**Example 16**Household bleach is 0.80 M NaClO. Find the concentrations of OH- and ClO- and the pH of household bleach.**Example 17**Find the pH of a solution that is 0.10 M CH3NH3OCl.**Example 18**Find the pH of a solution that is 0.10 M H3PO4.**Example 19**Find the pH of a solution that is 0.10 M NaH2PO4.**Example 20**Find the pH of a solution that is 0.10 M K2HPO4.
