Do a demonstration to introduce the concept of a precipitate – formation of a solid from the reaction of two liquids. Remind students that they have seen that mixing certain substances can result in a ...

Pour water into dish to a depth of ¼” to 3/8” Scoop a small amount of Pb(NO3)2 into the water at one side of the dish. Scoop a small amount of KI into the water directly opposite the Pb(NO3)2 A ...

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 ...

Chemical gardens are fascinating structures that form through precipitation reactions, where soluble ions react to create insoluble compounds that grow into intricate shapes. These processes are ...

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 ...

A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium ...
