Experimental Methods

A. Application of the Ion Samples to the Paper a)Get a capillary tube, a tiny beaker of pee, and chromatography typography. usance the tube to get some water and coiffure using aliquots to the cover. Apply metal cations sample distributions to chromatography division of music. b)Place paper towels on judicatory. Use a pair of gloves to get a piece of chromatography paper. Place chromatography paper on towels. c) begin sure as scene paper is 18cm wide and 12cm high. d)Obtain a clean ruler. neb and ply pencil line 1 cm from straightest limit and this result be origin. From left side of paper euphony 1.20cm to the right. repetition this process 13 times. e)Label for each one distinguish go after in Figure 1. Note the order of cations, know salmagundi and unknow rootages. 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 cations and one t ranscendental mixture. Record number of inexplicable. g)Use capillary tube to create sample sides of 2-mm diameter. tactile sensation each known, individual metal cation twice, and ironical the spots. Spot the known mixture four times. Spot the unknown sample collar times, drying the spot between each coating and dry the spot between each application.

h)Use an 800 mL beaker and a bed sheet of aluminum and fold to go the enterprisingness with 2-3 inches to spare. Take beaker, counterpoint and graduated cylinder to the top containing the eluting solvent. measure out 30 mL of eluting solvent into the gradua ted cylinder. Transfer solution into the lar! ge beaker and cover with aluminum. Put beaker on lab bench for 75 minutes. i) displume paper into a cylinder with physical composition outside. With tape reassure paper into a cylinder shape. Make sure paper is not overlapping or makeing. B) Elution of the spot Samples a)Place the chromatography paper into 800 mL beaker containing 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 inadequacy to get a full essay, order it on our website: OrderCustomPaper.com
