Organic Lesson 8 "Acids and Bases"
Science and Technology Standards:
PA Standard 3.4.12A
Purpose:
1. I will relate information of bonding, structure, and acid-base structure to acid-base theories to organic basic terms.
Homework Due:
1. 19 Electronegativity Problems
Handouts/Supplies:
1. No handouts
I. Introduction
Opening Assignment:
Warm-Up: What type of bond does HBr have?
Review warm-up
State the purpose
II. The Lesson:
Activity #1: Review 19 Electronegativity Practice Problems (*He and H)
Activity #2: Discuss types of acids and bases (2 sides of a coin)
Activity #3: Read Section 1.12 "Acids and Bases: The Bronsted-Lowry Definition"
Activity #4: Discuss the following: Bronsted-Lowry Acid
Bronsted-Lowry Base
Conjugate Acid
Conjugate Base
Hydronium Ion H3O+
Concentration [?] (Molarity/molality)
Acidity Constant, Ka (# = strong/weak)
pKa = -log Ka (# = strong/weak)
Inverse Relationship (strong acid->weak conjugate base/weak acid->strong conjugate base) Activity #5: Complete Section 1.12 Notes (Read p. 25)
Activity #6: Complete Practice pKa Problems
Activity #7: Complete Practice Problems #1.21, 1.22, 1.23, & 1.24
III. Closure:
Summary Assignment:
Summarize today's lesson
1. relate information of bonding, structure, and acid-base structure to acid-base theories to organic basic terms: What are the different definitions of acids and bases?
Homework Assignment (Write down in planners):
1. Practice Problems #1.21, 1.22, 1.23, & 1.24
