Lesson 4 Learning Targets – Determine the acid and base that contributed the anion and cation of a salt. Describe salt hydrolysis. Interpret whether a salt solution will produce an acidic, basic, or neutral aqueous solution. Lesson 4 Homework Problems – 3. Write the formulas for the acid and base which produce each of the following salts. Determine if each salt is acidic, basic or neutral. Salt Acid Base A/B/N Sodium Acetate Ammonium Nitrate Lithium Phosphate Potassium Nitrate Sodium Sulfate Lesson 5 Learning Targets – Explain that the Bronsted-Lowry definition of acids and bases still includes the Arrhenius acids and bases, but expands the number of substances that are considered acidic and basic. Use the and in describing Bronsted-Lowry acids and bases. terms “proton donor” “proton acceptor” Identify the acids and bases in an acid/base equilibrium reaction. Identify conjugate acid/base pairs in an equilibrium reaction. Explain why some substances are able to potentially behave like an acid and also like a base. Lesson 5 Homework problems – 1. Identify the conjugate acid-base pairs in the following reactions. a) NH4 + (aq) + OH (aq) NH3 (aq) + H2O (l) – b) HBr (aq) + H2O (l) H3O + (aq) + Br (aq) – c) CO3 2- (aq) + H2O (l) HCO3 (aq) + OH (aq) – – d) HSO4 (aq) + H2O (l) H3O + (aq) + SO4 2- (aq) –
