Answer: [SO42-] = 2.5 x 10^-2 / 0.020 = 1.25 M
The POGIL activity on fractional precipitation is designed to help students understand the concept of solubility and how it can be used to separate ions. The activity involves a series of questions and exercises that guide students through the process of fractional precipitation. fractional precipitation pogil answer key best
Answer: Ba2+ will precipitate first because BaSO4 has a lower solubility than CaSO4. Answer: [SO42-] = 2
Answer: 2.5 x 10^-2 M
