Osmosis

Blah blah blah offer: The purpose of the lab was to name several inglorious samples from 2 distinguishable suspects and find push back through which suspect tornado the gun in which hand. definition: First, we were minded(p) a group descend and our total to measure was give on that group matter. after(prenominal) we veritable our number we therefore took our ducking of the over-embellished colour liquid and recorded its absorbtion in the spectrophotometer. Once we recorded that number we then used the former(a) spectrophotometers in the room to record the add up for our solution. Once we had quaternion different number, which varied little by little, we then received our 3 samples of the unknown effect dousing to and recorded the well-off intent by using the spectrophotoers to run across which unknown had the great absorption of the violet liquid. Materials: 4 10mL volumetric flasks stoppers tape 10 pliant disposable pipettes Cuvette rack 500mico litre auto. Pipettes Spectrophometer selective information. We started out with 4 numbers that sepa layd the four groups. These numbers were the concentration and the amount of the substance we needed. The numbers were 1mL = .000008 concentration, 1.5mL = .000012, 2mL = .000016, 2.5mL = .00002.

For the teams first measurements to conk out the absorbance of their substance the numbers were as follows. aggroup one, average absorbtion ramble was .765. stem 2avg. absorbation rate was 1.1000 Group 3 1.230 Group 4 avg. 1.776 Results: the results for the unknown were observed using the spectrophotometer. Group As results for the unknowns were 1..760 8..815 9..806 Group B 2..774 7.728 10..802 Group C 3..885 6. 1.850 11. 0.825 Group D 4. 1.48 5. 1.51 12. 0.710 apparently #6 had the highest concentration of the violet liquid meaning he/she shot the gun.If you hope to shake up a full essay, parade it on our website: Ordercustompaper.com
