Quick Summary

Coprecipitation is the process where two or more substances precipitate together from a solution. This occurs when a substance is converted into an insoluble form or when the solvent's composition is altered to reduce a substance's solubility.12

While chemical precipitation focuses on forming a separable solid from a solution, coprecipitation involves the simultaneous precipitation of multiple components. This can happen when undesired constituents are incorporated into the crystals of a desired precipitate, affecting its purity. Techniques like homogeneous precipitation, where the precipitating agent is generated within the solution, can help minimize contamination.21
