A solution is made by adding 50.0 mL of 0.200 M acetic acid (Ka 1.8 105 ) to 50.0 mL of 1.00 103 M HCl. a. Calculate the pH of the solution. b. Calculate the acetate ion concentration.
CH 111 Notes: Week 12 Chapter 8: Chemical Bonds Electronegativity: (EN) the ability of an atom to attract electrons to itself when in a covalent situation o EN increases as you move up a group due to the growing size of the atom Larger atoms are less electronegative and smaller atoms are more electronegative o EN increases as you move left to right due to the growing effective nuclear charge Ionic Bonds: (metal and nonmetal) the attraction between a cation and an anion o Electrons are transferred, not shared o ∆EN ≥ 2 o Ex. Na Cl → Na + Cl EN = 0.9 3.0 ∆EN = 3.0 – 0.9 = 2.1 Covalent Bonds: (nonmetals) the sharing of electr
