By adding a reagent (like (Cl^-) ion) drop by drop, we can cause the ion with the to precipitate first, leaving the other in solution.

A crucial inquiry step asks: "How much of the first ion remains in solution when the second ion begins to precipitate?" You plug the Ag+cap A g raised to the positive power

POGIL activities are designed to build your mental model step-by-step. Do not jump straight to the math; answer the guiding questions about particle diagrams and trends first.

Fractional precipitation is a technique used to separate and purify mixtures of ions based on their solubility differences. The process involves adding a precipitating agent to a solution containing a mixture of ions, which causes one or more ions to precipitate out of the solution. By carefully controlling the concentration of the precipitating agent and the conditions of the reaction, it is possible to selectively precipitate specific ions in a mixture.

A solution contains ( \textBa^2+ ) and ( \textSr^2+ ), each at 0.10 M. You add ( \textNa_2\textSO 4 ) dropwise. (K sp(\textBaSO 4) = 1.1 \times 10^-10) (K sp(\textSrSO_4) = 3.2 \times 10^-7)
