POGIL activities are designed to show you that chemical separation is possible without physically filtering the beaker after every step; chemistry manages the separation natively based on thermodynamic limits.
Most POGIL problems assume the added reagent is so concentrated that the total volume of the solution doesn't change significantly.

At no point does the concentration of the first ion drop to absolute zero. Dynamic equilibrium ensures that a trace, calculable amount of the first ion always remains dissolved in the solution. 4. Key Takeaways for Exam Preparation fractional precipitation pogil answer key best
Answer: [SO42-] = 1.1 x 10^-5 / 0.020 = 5.5 x 10^-4 M

: Usually involves a solution containing multiple cations, such as Zn2+cap Z n raised to the 2 plus power Cu2+cap C u raised to the 2 plus power , and a titrant like sodium carbonate ( Na2CO3cap N a sub 2 cap C cap O sub 3 ) being added dropwise.
