Lecture #3: Friday, April 1st
Fractional/Selective precipitation was introduced and several example problems were used to illustrate when a ppt would form and how to effective separate two (or more) ions in solution. With the lectures notes from today you should be able to complete the following problems:

Precipitation Tutorial
Selective Precipitation Tutorial
Precipitation Calculation Tutorial
Fractional Precipitation of Metal Carbonates Tutorial
*Solubility Quiz Question #3
