Gold Chemical Separation Methods

One of the most important and time consuming activities in chemistry involves isolating, separating, and purifying chemical compounds. Extraction (literally, taking out by force ) is a useful technique for separating compounds such as I 2 and KMnO 4 that have different polarities. The compounds to be separated are treated with a mixture of a polar solvent (such as H 2 O) and a nonpolar.
