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 ...

Place petri dish on stage of overhead projector. 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 ...

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 ...

Students investigate reactions which produce a gas, form a precipitate, and cause a color change. Students also explore endothermic and exothermic reactions and do an engineering activity to design a ...

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 ...
