Investigating the solubilities of lead halides

Description

The halogens are elements of Group 17 of the Periodic Table. This experiment illustrates some of the trends within the compounds of this group. It is ideal for discussing ionic equations, making predictions and understanding the solubility patterns amoung common ionic compounds.
