BaSO4 (s) → Ba2+ (aq) + SO42- (aq) CaSO4 (s) → Ca2+ (aq) + SO42- (aq)

This isn't just a classroom exercise. Fractional precipitation is vital in: Wastewater Treatment: Removing toxic heavy metals one by one. Chemical Manufacturing: Purifying reagents by removing specific contaminants. Forensics and Analysis: Identifying the presence of specific halides in a sample. Troubleshooting Your Answers When checking your work against a key, keep an eye on stoichiometry . If your salt is cap A g sub 2 cap C r cap O sub 4 , remember that your cap K sub s p end-sub expression is fractional precipitation pogil answer key 2021

is added dropwise, the ion that forms the least soluble salt (lowest Kspcap K sub s p end-sub ) precipitates first. BaSO4 (s) → Ba2+ (aq) + SO42- (aq)

The process of choosing a specific concentration of an added ion to remove one metal ion while leaving others in the solution. Key Concepts in the 2021 POGIL 1. Determining the Order of Precipitation Forensics and Analysis: Identifying the presence of specific
