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 100mm petri dish containing water is placed on an overhead projector. When solid Pb(NO 3) 2 is place on one side and solid KI on the other, PbI2 precipitates in the center.

Serves as a continuation of the laboratory study begun in CHEM.1230L that is coordinated with topics of CHEM.1220. Topics include: thermochemistry, kinetics, spectroscopy, titration, pH, equilibrium ...
