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.

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 ...

Substances have characteristic chemical reactions that can be used to identify a substance ... soap solution with the Epsom salt solution to produce a solid “soap scum” precipitate. Students then ...

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 explore the concept that chemical reactions involve the breaking of bonds between ... Students investigate reactions which produce a gas, form a precipitate, and cause a color change.
