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 ...

Students will be able to explain that mixing substances can cause a chemical reaction that results in the formation of a new substance. Students will be able to plan and carry out an investigation to ...

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

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 ...

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 scaleable method for the liquid-phase separation of plasmid DNA from RNA. In the course of experiments on the potential of nucleic acid compaction for enhancement of chromatographic adsorption ...
