Unit 9 - Acids and Bases

Key Objectives: 

• Be able to describe Arrehnius acid-bases
• Be able to describe Bronsted-Lowry acid-base
• Be able to identify conjugate acid-base pairs
• Be able to write and explain the autoionization of water
• Be able to calculate pH given concentration of a strong acid or base
• Be able to calculate concentration given pH
• Be able to use Ka of a weak acid to determine pH
• Be able to explain titration
• Be able to calculate neutralization reactions from a titration

Big idea: acids and bases are simply the movement of a proton.

- Acid-Base introduction (Slides)
- Equilibrium of acid dissociation - strong vs weak acid (PhET acid-base)
- Bronsted-Lowry Acid Bases (Pogil, practice 1, practice 2)

- Titration of a strong and weak acid (Lab)
- Neutralization through titration (Lab)
- Titration of weak acid and excess conjugate base (Lab)
