: You can calculate the percentage of the first ion remaining in the solution when the second ion just begins to precipitate. If this percentage is very low (e.g., ), the separation is considered "complete". Khan Academy Solving Fractional Precipitation Problems To solve these mathematically, follow these steps: Set up the cap K sub s p end-sub expression for each possible solid: Solve for the unknown ion concentration
