WebFeatures of Pierce strong ion exchange spin columns: • Fast and simple —membrane-based spin format eliminates column packing • Convenient and expandable —centrifugal format enables convenient processing of … Webrecombine and form new molecules of water. To do this, you need a cation exchange resin in the H form and an anion exchange resin in the OH form. All cations and anions will be exchanged, and in this case the net result is a complete “disappearance” of the ionic contaminants. The cation exchange reactions will be: 2 R’H + Ca++R cool school prizes for elementary kids
