In a fractional precipitation process, multiple ions in a solution are separated by the selective addition of a common precipitating agent
When a reagent is added to a solution containing multiple ions, it will react with all of them to form potential precipitates. However, the precipitates do not form simultaneously. The compound with the lower solubility will reach its saturation point first and begin to precipitate out of the solution, while the more soluble compound remains dissolved until a higher concentration of the precipitating ion is added.
