What is a precipitate, and how can they be used to separate solutes?
A precipitate is a solid or a solid phase that separates from solution.
Typically, chemists exploit differential solubilities when using precipitation reactions.
All salts of the halides are soluble, except for those of
Actually I can be even more concise than this because the sodium and nitrate ions are simply along for the ride, and do not undergo chemical change in solution. Thus I can write the net ionic equation:
Of course, you have to know which salts are soluble, and thus which mixtures will produce an insoluble salt. There should be many resources here and on the web. Good luck.
