Supersaturation is the driving force for crystal nucleation and growth. For example, when a solution of iron chloride and ammonium hydroxide are mixed, a brown precipitate of iron hydroxide is formed. When solubility is reduced, the solution will become supersaturated. “Precipitate Definition and Example in Chemistry.” ThoughtCo, Jan. What is precipitation reaction explain with example When two reactants in solution react and one or more of the products is insoluble or forms a precipitate, the reaction is called a precipitation reaction. “Decantation Definition in Chemistry.” ThoughtCo, Aug. Helmenstine, Anne Marie, “Supernate Definition in Chemistry.” ThoughtCo, Jan. However, the key difference between supernatant and precipitate is that supernatant is in liquid form, whereas precipitate is in solid form. Wherever a supernatant form, a precipitate also forms. In summary, the supernatant and precipitate are two related terms. while the precipitate forms from the reaction between two salts, by changing the temperature of a solution, by centrifugation, etc.īesides, a further difference between supernatant and precipitate is that we separate a supernatant mainly via decantation, whereas we can separate the precipitate from the reaction mixture using filtration, decantation, and centrifugation. Moreover, when considering the cause of formation, supernatant forms during centrifugation, crystallization, precipitation, etc. Supernatant forms above the precipitate or sediment while the precipitate forms at the bottom of the container. The key difference between supernatant and precipitate is that the supernatant is in liquid form, whereas the precipitate is in solid form. What is the Difference Between Supernatant and Precipitate? Supernatant and precipitate are two related terms.What is the Relationship Between Supernatant and Precipitate?

The techniques in which we can find the term supernatant are centrifugation, precipitation, crystallization, etc. Sometimes, we call it a supernate as well. The supernatant is the liquid we can observe above a solid precipitate. Side by Side Comparison – Supernatant vs Precipitate in Tabular Form

At the end of the process, the particles will form a precipitate at the bottom of the centrifuge tube while the latter remains as a supernatant. In this process, we have to prepare a suspension and place it in a centrifuge tube, which is placed on a rotor to make it spin at a particular speed. The separation can be done according to the size, shape, density or viscosity of these particles. The key difference between supernatant and precipitate is that supernatant is in the liquid form, whereas precipitate is in the solid form.Ĭentrifugation is an analytical technique we use to separate particles from a solution.
