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 ...

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 ...

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 ...

Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests or reaction with dilute ... acid and then into the solid ionic compound which is sitting in a watch glass.
