Below are responses generated using the isolated guinea-pigileum preparation to determine a pA₂ value for the cholinergicantagonist homatropine.Responses are expressed in millimetres +/- SDM (n = 4).Plot the data and then determine by Schild analysis the pA₂ valueand Schild slope.So that's TWO drawn graphs to plot on LIN/LOG paper andsubmit..not EXCEL graphs please.What conclusions can you draw; does the experiment/data fulfil thecriteria for a valid Schild analysis?AcetylcholineACHAloneConcentrationACH +ACH +ACH +Homatropine Homatropine Homatropine3 x 10-⁹M1 x 10-M3 x 10-M[Molar]3 x 1093 +/- 16 x 1098 +/- 3No response3 x 10-828 +/- 610 +/- 4No response6 x 10838 +/-821 +/-95+/-2No response3 x 10-755 +/- 543 +/- 727 +/-910 +/- 46 x 10-756 +/- 552 +/- 338 +/- 720 +/-73 x 10-655 +/-453 +/- 643 +/- 66 x 10656 +/-254 +/- 5

The concentration of acetylsalicylic acid in an antipyretic tablet was determined by HPLC using a normal calibration curve. Standard solutions of acetylsalicylic acid were prepared and analysed using a 10µL loop. The results obtained for the standards are tabulated below: Conc. of Acetylsalicylic Acid (ppm); Signal (arbitrary units) 50; 6352 100; 12869 150; 19175 200; 25536 250; 31936 To determine the concentration of acetylsalicylic acid in an antipyretic tablet, 10 tablets were weighed (6.500 g total) and crushed to a fine powder using a mortar and pestle. A quantity of powder equal the mass of one tablet was added to a 100 mL volumetric flask. The tablet powder was dissolved with 20 mL of methanol and the flask was made to volume using water. The solution was filtered. A 1.000 ml aliquot was transferred to a 10 ml volumetric flask, which was then made to volume with water. Analysis was conducted using a Bio Sil HL C18, 250mm x 4.6mm column; 5um, with a mobile phase of acetonitrile:…
(2) Sally starts eluting her column with petroleum ether in hopes of separating her 50:50 ferrocene: fluorenone mixture. She notices her mobile phase getting low when there is limited separation between her two components. She eagerly adds more solvent to avoid her column from drying out. Sally then realizes she poured from her 1:1 petroleum ether: diethyl ether beaker rather than her petroleum ether beaker. (a) Using the molecular view below, explain how this would impact her product elution from the column. top of column H buret wall AI H H H H H H H H H H bottom of column buret wall (b) How does this error impact her experimental results? (c) Using pictures and words, how could Sally analyze the purity of her product? Fe
If the endpoints you reached during standardization of your NaOH solution were very precise (relative average deviation if 0.03%) but were all overshot (meaning too much NaOH was added an you passedyour equivalence point), is the reported molar concentration of the acid solution from this experiment greater than , less than or equal to the true concentration? Explain.
Following the monograph procedure, a 724-mg of aspirin (MW=180 g/mol) dissolved in 18.5 ml of cold neutralized alcohol. This solution was then initially titrated with 0.101 N sodium hydroxide solution, then later neutralized with 0.104 sulfuric acid. What is the percentage purity of the sample? 1. What is the milliequivalent weight consumed by the acidic titrant? a. 1.5392 g-meq b. 2.0907 g-meq c. 1.4948 g-meq d. 2.1528 g-meq 2. What is the milliequivalent weight consumed by the basic titrant? a. 5.8656 g-meq b. 1.5392 g-meq c. 5.6964 g-meq d. 1.4948 g-meq 3. What is the difference of milliequivalent weight consumed in the reaction? a. -4.1572 g-meq b. 4.3708 g-meq c. 0.5515 g-meq d. 4.1572 g-meq
Can you help me to support this? Based on your observations of your TLC plate and FeCl3 tests, how pure is your aspirin?
2. Prepare a Temperature vs Time cooling curve for each of the two trials involving the lauric acid/stearic acid mixtures. Perform a linear regression analysis on the cooling and freezing regions as before. Calculate the point of intersection and identify this point on each graph by inserting a text box and arrow. Report the freezing point for each of the two trials [T(1) and T (2)]. Freezing point (1st trial of lauric acid) T(1) = Freezing point (2nd trial of lauric acid) T(2) =
