Learn more about the definition, examples & equations of precipitation reaction. precipitate verb (CHEMISTRY) [ I or T ] chemistry specialized If a liquid precipitates, substances in it become solid and separate from the liquid: Cooling the beaker helps precipitate the compound. This chemistry video tutorial explains how to balance and predict the products of precipitation reaction in addition to writing the net ionic equation. This One way is to include notations and parenthesis that tells you what state the chemicals are in. AQ meaning aqueous or insolution and S for solid meaning that it's your precipitate.
In precipitation, the solute particles find each other and form a solid together. Chemical precipitation is the most common technology used in removing dissolved (ionic) metals from solutions, such as process wastewaters containing toxic metals. The ionic metals are converted to an insoluble form (particle) by the chemical reaction between the soluble metal compounds and the precipitating reagent. In most methods the precipitate is the product of a simple metathesis reaction between the analyte and the precipitant; however, any reaction generating a precipitate can potentially serve as a gravimetric method. Most precipitation gravimetric methods were developed in the nineteenth century, or earlier, often for the analysis of ores. Precipitation refers to a chemical reaction that occurs in aqueous solution when two ions bond together to form an insoluble salt, which is known as the precipitate.

** A precipitate is an insoluble solid that separates from the solution. Precipitation reactions usually involve ionic compounds. ** For example, when an aqueous solution of lead(II) nitrate [Pb(NO 3) 2] is added to an aqueous solution of potassium iodide (KI), a yellow precipitate of lead(II) iodide (PbI 2) is formed:
[3] Precipitates are insoluble ionic solid products of a reaction, formed when certain cations and anions combine in an aqueous solution. The determining factors of the formation of a precipitate can vary. Some reactions depend on temperature, such as solutions used for buffers, whereas others are dependent only on solution concentration. White solid particles will form and deposit as a precipitate. Tell students that a chemical reaction took place and that a solid was formed.
Precipitates can form when two soluble salts react in solution to form one or more insoluble products. Learn precipitation reactions chemistry with free interactive flashcards.
