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 ...

Scoop a small amount of KI into the water directly opposite the Pb(NO3)2 A precipitate of PbI2 will form near the center of the dish.

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 ...

Can be used to recap on precipitation reactions or could lead into a classroom discussion on chemistry in society.
