2. Overview Indicators for Titrations Strong Acid/Strong Base Case
Weak Acid/Weak Base Case

3. Titration Basics
Indicators include weak organic acids or bases that display different colors based on pH.

7. Strong Acid/Strong Base Case
Use ICE table method from general chemistry to solve these problems.
Before equivalence point pH is calculated from the molar concentration of unreacted acid or base.
At equivalence point, pH is always equal to 7.00

11. Weak Acid/Weak Base Cases
Weak acid & weak base titrations are solved using the ICE table method from general chemistry.
Initial pH
Calculate pH after addition of acid or base using titration equation
Equivalence point pH
Beyond equivalence point (excess titrant left)
