Step 1

It is a selective separation process where some ions are removed from a solution by precipitation, leaving other ions with similar properties in the solution. This is done by taking advantage of the different solubilities of the compounds under different Show more…

Key Concepts

Fractional Precipitation

Fractional precipitation is a separation technique used to isolate ions or compounds from a solution based on slight differences in their solubility. By carefully controlling the addition of a precipitating agent, the compound with the lowest solubility is selectively precipitated first, leaving others in solution. This gradual approach allows for the sequential separation of species from a mixture.

Precipitation Reactions

Precipitation reactions occur when a soluble compound reacts with another reagent to form an insoluble product, known as a precipitate. These reactions are governed by the solubility rules and the solubility product (Ksp), which determine the conditions under which a compound will begin to precipitate from solution.

Solubility and Solubility Product (Ksp)

Solubility is the property that defines how much of a substance can dissolve in a given solvent at a specific temperature. The solubility product (Ksp) is a constant that quantifies the equilibrium between a solid and its ions in a saturated solution. In fractional precipitation, differences in Ksp values among compounds are exploited to achieve selective precipitation.
