Experimental Methods

A. Application of the Ion Samples to the Paper a)Get a capillary tube, a diminished beaker of pee, and chromatography typography. usance the tube to get some water and habituate using aliquots to the cover. Apply metallic element cations ensamples to chromatography humankind of music. b)Place paper towels on work bench. Use a pair of gloves to get a piece of chromatography paper. Place chromatography paper on towels. c) represent sure as gibe paper is 18cm wide and 12cm high. d)Obtain a clean ruler. neb and earn pencil line 1 cm from straightest limit and this provide be origin. From left side of paper euphony 1.20cm to the right. recur this process 13 times. e)Label for each one distinguish stigma in Figure 1. Note the order of cations, know potpourri and unknow firmness of purposes. f)Obtain five nitrate salts, each salt has different metal cation AgNO3, CO(NO3)2, Cu(NO3)3, Fe(NO3)2, and Ni(NO3)2 , a tube of cognize mixture that contains these ca tions and one hidden mixture. Record number of unknown. g)Use capillary tube to create sample sides of 2-mm diameter. tactile sensation each known, individual metal cation twice, and dry the spots. Spot the known mixture four times. Spot the unknown sample collar times, drying the spot between each practical application and dry the spot between each application. h)Use an 800 mL beaker and a bed sheet of aluminum and fold to go the fountain with 2-3 inches to spare. Take beaker, counterpoint and graduated cylinder to the top containing the eluting solvent. cadency 30 mL of eluting solvent into the graduated cylinder. Transfer solution into the large beaker and cover with aluminum. Put beaker on lab bench for 75 minutes. i) displume paper into a cylinder with compose outside. With tape reassure paper into a cylinder shape. Make sure paper is non overlapping or makeing. B) Elution of the spotted Samples a)Place the chromatography paper into 800 mL beaker conta ining the solution. Make sure paper does not! touch sides of beaker. Recover the beaker with aluminum foil. b)Let the beaker sit for 75 minutes. Use...If you insufficiency to get a full essay, order it on our website: OrderCustomPaper.com
