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

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"
