Jonathan Retta Desk # Kristin C. Halfpenny Thursday 9:35-12:25 States of Matter Sleuth Introduction The objective of this lab was to determine, via methods of visual inspection, conductivity, melting points, solubility, and ion-exchange chromatography, the unknown compounds given. Four different bottles were given: a heterogeneous mixture, a covalent compound, an ionic compound, and a pure element. By knowing these values, it was then determined which bottle contained the ionic compound, and which cation it was. Procedure The lab began by first grabbing one of the six unknown salts that could have been the ionic compound. Then a portion was measured out and mixed into some deionized water. The solution was then combined and added to the Amberlite resin, which would figure out the acidity level of the solution, which could then determine its contents. Water was added to the Amberlite resin, until completely filtered. After filtered, the unknown ionic compound was added to the solution, which was to be filtered through the
