determine the products. All you need to do is pair the positive parts of the compounds with the other compounds negative part. Once you find the products you can determine their phase of matter by using Table H. You can also use Table F to determine the solubility guidelines for aqueous solutions. If the product falls under soluble or exceptions to insoluble it is in the aqueous stare. If the product falls under insoluble or exception to soluble it is a precipitate. Once you have completed those steps you

Usually an aqueous and organic phase are used. During extraction the desired compound moves one phase and leaves the unwanted substance behind. Extraction normally has to be done a few times to leave all of the impurities
