Chemical precipitation is an effective treatment process for the removal of many contaminants. Coagulation with alum, ferric sulfate, or ferrous sulfate and lime softening both involve chemical ...

Below is an example of a precipitation reaction. Notice the two aqueous solutions make a solid substance. \(AgNO_{3}(aq) + NaCl(aq)\rightarrow AgCl(s) + NaNO_{3}(aq)\) If state symbols are not ...

Since a precipitate is a solid it can be collected by filtering. The precipitate is left behind on the filter paper as residue which can be washed by pouring water over it when it is still in the ...

Many solids precipitate or fall out of a solution when another component or chemical is introduced to the solution, causing a chemical reaction. Other solids form when a solution is supersaturated by ...
