an Iron Oxalate Salt by Ion Exchange Introduction: This experiment involves determining both the percent potassium (K) and iron (Fe) in a single titration after passing a solution containing a known mass of complex salt through an ion exchange column. Ion Exchange: Certain materials called ion exchange resins consist of rather large molecules which contain ions that can be displaced. The resins are solids‚ insoluble in water‚ usually granular in texture‚ which when added to water swell to form

technique book provides a detailed description of how to run a ion- exchange column. Assume you have a cation-exchange column already prepared and ready to use. Create an outline of no more than 10 steps describing how you will regenerate the column‚ load your sample and collect the hydronium ion released. 1. Open the stopcock at the bottom of the column and allow solution to drain out until the solution level in the column is exactly level with the top the resin; then close the stopcock. 2. Obtain

Experiment 5 Analysis of Plant Pigment Purpose: Chromatography is used for separation. In this case the separation of plant pigments. After placing the plant sample in the column the separation will be easy to see and the samples will be analyzed using VIS spectrophotometry. This is used to isolate and identify the different lipids causing the different pigmentations. Introduction: Lipids are chemically diverse substances found in cells. Lipids are water-insoluble‚ structural components
