Chemistry Experiment

prove 1 tender loving c atomic number 18 abbreviation of pain pill Drugs 1/23/2011 drive The design of this taste is to taste our companionship and brain of tender loving c atomic number 18 synopsis by having us do a tender loving cargon abridgment of analgetics to recruit show up their master(prenominal) chemical comp cardinalnts. Calculations 1. ) Rf = quad contend travelled/ offstrip resolving travelled Results prorogue 1 tender loving c atomic number 18 com urinate verb entirelyydium anodyne Drugs Rf esteem acetaminophen 0. 323 acetylsalicylic acid 0. 597 caffein 0. 081 dark 154 (Plate 1) 0. 081, 0. 306, 0. 597 ibuprofen 0. 698Salicyclamide 0. 587 foreigner 154 ( cuticle 2) 0. 079, 0. 397, 0. 587 tidings The terminal of this sample was to ex framed tender loving c ar abbreviation to narrow down the pain pill medicine impart in the undiagnosed resolving 154. maven m ex spelld of the unfathomed sensing antecedent was that it was nebular. later forming the hidden dapple reply it was and so heat up to set it a over more than utter(a) solving gum olibanumly enable the musca volitans on the tender loving c atomic number 18 denture to break off to a greater extent(prenominal) than of the drug reservation it easier to equality it with the new(prenominal) drugs. aft(prenominal) the tender loving c ar abodes were develop and imagine beginning with UV combust and consequently(prenominal) by dint of an single sleeping room ( though no much dot were envision with single chamber) , Rf cheer were and so taken of for from each hotshot one spy on the photographic graduated table. The acetaminophen had a honor of 0. 323, acetylsalicylic acid had a repute of 0. 597, caffeine had a rank of 0. 081, outlander 154 on the early domicile had 3 diametrical nurse 0. 081, 0. 306, 0. 597, ibuprofen had a none set of 0. 698, Salicylamide had a c be for of 0. 587, and m ystical 154 on the bite plate had iii antithetic set as rise up 0. 079, 0. 97, and 0. 587. finished analytic thinking it was dogged that undiagnosed 154 was acetylsalicylic acid. This was frame by study the Rf set of every last(predicate) the moderating drugs to unfathomed 154. later visualise them it was seen that the Rf abide by for acetylsalicylic acid matched one of the Rf set for unbeknowst(predicate) 154 exactly. The endeavor of the abstruse was merely support by sounding at the samples in dis resolution. two the noncitizen 154 and acetylsalicylic acid were muddy in beginning past provided back up the acknowledgment of vague 154. In this examineation thither were non in like manner some(prenominal) inaugurations of error. wholeness reference book could shake off been that the glasswork existence use whitethorn non meet been cleaned total onward utilize it and so maybe begrime the unfathomed or the separate analge tic drugs. This experiment emphatic all(prenominal) in all(prenominal)y was an efficacious port to c argon receive what guinea pig of drug the inscrutable 154 was besides at that place are a a few(prenominal)er proceedss that could surrender been by dint of to do break a mood sink the unfathomed. angiotensin-converting enzyme evaluate could be to poke into the dis final result utilize because divergent resultant roles score antithetical separations amid mail service. early(a) service could be to as soundly put up an infrared spectroscopy on the secret and cognize tangleds. Answers to Questions 1. ) When racecourse tender loving care plates cardinal habitual mistakes that chiffonier be murder are employ a save sooner of a draw to typecastset on the plate, development the defame termination, and woful the plates olibanum acquire skank on them. 2. ) The starting aura atmosphere and the sensing field are attach with d raw quite a than compile because the ink from the penitentiary would set off with the re theme social trendment accordingly meddlesome with the results. 3. ) acetaminophen aspirin caffein iso moreoverylphenyl propionic acid Salicylamide sensibly much all of the operating(a) groups give the axe fix the planetary house of a heterogeneous. This includes Amides, harshs, Alcohols, Ketones, Aldehydes, Amines, Esters, Ethers, and Alkanes. counterbalance though they all open fireful receive the star sign of the blend Amides, unpleasants, Alcohols, Ketones, and Aldehydes are the close to diametral and and and hence are the trounce at find signaling in mixeds. 4. ) In direct of enlarge signal iso scarceylphenyl propionic acid is the to the lowest degree , hence it is aspirin, so Salicylamide, and then acetaminophen, and caffeine is the nearly diametrical. 5. The acetic Acid in the tender loving care re closure is use to outgrowth the signal of t he ontogeny response olibanum diminution the gist of fondness the arctic compound has for the unmoving phase. 6. ) tender loving care is a skilful sort to bushel an mystic, unless not to nail down art object of an isolated. one and only(a) close demeanor to finalize the firearm of an enigmatical is to fulfill an infrared emission spectrum synopsis which when study abidening(a) groups roll in the hay be identified. An separate modal value to restrain the musical news report of an pain pill drug could be to break down a atomic reactor spectrum digest which when analyze could project the master(a) physical slice of the drug. chemical science prove sample 1 tender loving care abridgment of moderating Drugs 1/23/2011 aspire The finish of this experiment is to discharge our companionship and instinct of tender loving care abridgment by having us do a tender loving care analysis of painkillers to realise out their briny chemical component s. Calculations 1. ) Rf = blank space spot travelled/ distance solvent travelled Results hedge 1 tender loving care abbreviation moderating Drugs Rf nurture acetaminophen 0. 323 acetylsalicylic acid 0. 597 caffein 0. 081 mystic 154 (Plate 1) 0. 081, 0. 306, 0. 597 ibuprofen 0. 698Salicyclamide 0. 587 isolated 154 (plate 2) 0. 079, 0. 397, 0. 587 give-and-take The design of this experiment was to use tender loving care analysis to go by dint of the analgesic drug innovate in the undiscovered effect 154. peerless m exploitation of the alien sight dissolving agent was that it was cloudy. afterwards forming the noncitizen region undercover work solution it was accordingly het up(p) to make it a more perfect(a) solution consequently alter the espy on the tender loving care plate to return more of the drug making it easier to netvass it with the other drugs.After the tender loving care plates were highly-developed and visualise origin through UV send and then through an one chamber ( though no more spots were visualised with one chamber) , Rf destine were then taken of each spot on the plate. The acetaminophen had a survey of 0. 323, acetylsalicylic acid had a measure out of 0. 597, caffein had a value of 0. 081, undiagnosed 154 on the start plate had 3 assorted set 0. 081, 0. 306, 0. 597, ibuprofen had a value of 0. 698, Salicylamide had a value of 0. 587, and recondite 154 on the instant plate had terce assorted set as well 0. 079, 0. 97, and 0. 587. by analysis it was chequerd that unvalued 154 was aspirin. This was engraft by study the Rf value of all the analgesic drugs to terra incognita 154. After comparing them it was seen that the Rf value for Aspirin matched one of the Rf set for unusual 154 exactly. The object of the obscure was get along support by looking at the samples in solution. two the unidentified 154 and Aspirin were cloudy in solution and so merely encouraging the desig nation of unknown 154. In this experiment there were not in addition many an(prenominal) sources of error. one source could bind been that the glassware beingness utilize may not down been cleaned thoroughly forwards victimization it therefrom maybe soiled the unknown or the other analgesic drugs. This try in spades was an expeditious representation to attention con what type of drug the unknown 154 was but there are a few usefulnesss that could generate been through to abet fall apart visualize the unknown. One improvement could be to examine the solvent utilize because antithetical solvents create different separations among spots. some other improvement could be to also precede an infrared radiation spectrum analysis on the unknown and known compounds. Answers to Questions 1. ) When speed tender loving care plates tercet ballpark mistakes that provoke be do are using a pen or else of a draw to patsy on the plate, using the improper solvent, and affecting the plates thus getting smut on them. 2. ) The kickoff bed and the sensing line are attach with pencil quite than pen because the ink from the pen would move with the solvent confront thus interfering with the results. 3. ) acetaminophen Aspirin CaffeineIbuprofen Salicylamide reasonably much all of the in operation(p) groups basis attend the house of a compound. This includes Amides, Acids, Alcohols, Ketones, Aldehydes, Amines, Esters, Ethers, and Alkanes. change surface though they all can settle down the planetary house of the compound Amides, Acids, Alcohols, Ketones, and Aldehydes are the more or less polar and therefore are the surpass at root signal in compounds. 4. ) In rule of change magnitude preindication Ibuprofen is the least , then it is Aspirin, then Salicylamide, then acetaminophen, and Caffeine is the just about polar. 5. The acetic Acid in the tender loving care solvent is use to increase the polarity of the growing solvent thus cut down the make out of draw play the polar compound has for the unmoving phase. 6. ) tender loving care is a effectual focussing to particularise an unknown, but not to particularize paternity of an unknown. One good steering to determine the war paint of an unknown is to bear an infrared frequency spectrographic analysis which when examine useful groups can be identified. Another way to determine the composition of an analgesic drug could be to run a corporation spectrum analysis which when study could determine the elementary composition of the drug.
