![]() MgF 2 and ZnSO 3 are both precipitates in this reaction.The other possible product is KCl which is soluble. Therefore this is NOT actually a precipitation reaction. The two possible products are LiCO 3 and NaNO 3 neither of which is insoluble. The other possible product is Ca(ClO 3) 2 which is soluble. The other possible product is CaF 2 which is soluble. By looking at our solubility rules or a solubility table we can check which ones will form a precipitate. Predict the precipitate(s) in the following precipitation reaction examples. Video showing an example of a precipitation reaction Precipitation Reaction Example Problems ![]() Near deep-sea hydrothermal vents, many minerals precipitate, particularly sulfides, leaving behind huge chimneys on the ocean floor. Nature also makes some cool precipitate structures. For those tests, a series of compounds can be added to deduce what ions are present. ![]() Additionally, these tests are also commonly used in chemistry labs. The lead would precipitate out as either PbCl 2 or Pb(OH) 2 and indicate that lead is present. For example, to determine if lead (Pb 2+) is present in the solution, a solution containing chlorides or hydroxides could be added. Precipitation reactions are commonly used to identify if certain ions are present in a solution. To learn how to name these compounds, read the Naming Ionic Compounds tutorial!
