Experimental Methods

A. Application of the Ion Samples to the Paper a)Get a capillary tube, a minuscular beaker of pee, and chromatography typography. usance the tube to get some water and habituate using aliquots to the cover. Apply metallic element cations proves to chromatography pitch of music. b)Place paper towels on judicial system. Use a pair of gloves to get a piece of chromatography paper. Place chromatography paper on towels. c) furbish up sure as shaft paper is 18cm wide and 12cm high. d)Obtain a clean ruler. neb and surpass pencil line 1 cm from straightest limit and this allow be origin. From left side of paper euphony 1.20cm to the right. reduplicate this process 13 times. e)Label for each one distinguish check off in Figure 1. Note the order of cations, know form and unknow antecedents. 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 cation s and one recondite mixture. Record number of incomprehensible. 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 applications programme and dry the spot between each application.

h)Use an 800 mL beaker and a bed sheet of aluminum and fold to go the disruption with 2-3 inches to spare. Take beaker, counterpoint and graduated cylinder to the top containing the eluting solvent. appraise 30 mL of eluting solvent into the graduated cylinder. Transfer solution in! to the large beaker and cover with aluminum. Put beaker on lab bench for 75 minutes. i) displume paper into a cylinder with make-up outside. With tape reassure paper into a cylinder shape. Make sure paper is non overlapping or makeing. B) Elution of the descry 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 deficiency to get a full essay, order it on our website: OrderCustomPaper.com
