To determine if the separation was successful, calculate the percentage of the first ion remaining in solution:
To predict whether a precipitate will form, chemists compare Kspcap K sub s p end-sub : The solution is unsaturated. No precipitate forms.
Begin by writing the balanced chemical equations for the dissolution of both potential precipitates. This ensures you know the correct ion ratios. fractional precipitation pogil answer key best
Ksp=[Ag+][I−]cap K sub s p end-sub equals open bracket cap A g raised to the positive power close bracket open bracket cap I raised to the negative power close bracket
AgCl requires much less Cl⁻ → AgCl precipitates first . To determine if the separation was successful, calculate
"I... well, I might have used a different source for the constants," Derek stammered.
). By carefully controlling the concentration of the precipitating agent, you can crash one ion out of the solution while keeping the others dissolved. 1. The Core Principle: Kspcap K sub s p end-sub This ensures you know the correct ion ratios

value. You must calculate the exact concentration of the common ion required, as shown in Step 1.
