Answer: The molar ratio of Ba2+ to Ca2+ in the precipitate is 1:0, because only Ba2+ precipitates.
Answer: [SO42-] = 2.5 x 10^-2 / 0.020 = 1.25 M fractional precipitation pogil answer key best
Answer: 1.1 x 10^-5 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. Answer: The molar ratio of Ba2+ to Ca2+
