If you'd like to work through a specific problem from your worksheet, tell me: The in your solution (e.g., Ba2+cap B a raised to the 2 plus power Sr2+cap S r raised to the 2 plus power The precipitating agent being added The Kspcap K sub s p end-sub values provided in your table
The POGIL exercise often asks which ion will precipitate first.
Find the concentration of the added ion needed to start the second precipitation. Step B: Plug that concentration back into the Kspcap K sub s p end-sub
The ion that requires the concentration of the added reagent is the one that precipitates first. 3. Separation Efficiency
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
value. You must calculate the concentration of the added ion needed for each potential precipitate. 2. Calculating Minimum Concentration
