Organic Lesson 9
"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. Practice Problems #1.21, 1.22, 1.23,
& 1.24
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 Practice pKa Problems
and Practice Problems #1.21, 1.22, 1.23, & 1.24
Activity #2: Discuss the inverse relationship (strong acid->weak conjugate
base/weak acid->strong conjugate base)
Activity #3: Review 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 #4: Read Section 1.13 "Acids and Bases: The Lewis Definition"
Activity #5: Discuss the following:
Lewis Acid
Lewis Base
Activity #6: Complete Section 1.13 Notes
Activity #7: Complete Practice Lewis Acid Problems
Activity #8: Complete Practice Problems 1.25 & 1.26
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. Complete Section 1.13 Notes
2. Complete Practice Lewis Acid Problems
3. Complete Practice Problems 1.25 & 1.26
