Try a little harder in seraching. I think the main use for it is to obtain a useful substance in 2 soluable solutions that would react. I am not sure I am in year 10.

Umm.. if that's the same as the use of solubility rules.. would water testing count? For example if a factory was based near a water supply or a river or something, and it was suspected that runoff was leaking into the river, solubility, or precipitation reactions could determine what was in it. Like if it was silver chloride or something.
Not sure if that was of any help at all. :/
