If aspirin were taken in a syrup instead of a tablet, how would this affect an excipient analysis? Specifically, what result would you expect from the IKI test?

Expert Solution

Aspirin or acetylsalicylic acid (ASA) is a commonly used drug for the treatment of pain and fever

IKI test, also called Iodine test, is iodine solution made up by dissolving iodine (I ) in a solution of potassium iodide (KI). It has a light orange-brown color. When Iodine is added to the sample containing starch it turns dark blue-black in colour, showing the presence of starch.

To obtain the characteristic shape in the Commercial aspirins (tablets), starch is added to it. Therefore when Iodine test is performed on a tablet, the light orange brown colour changes to dark blue-black colour

However, since aspirin syrup would not contain starch in it, it will show negative results for Iodine test, and no change in colour will be observed

Aspirin tablet + Iodine solution → Change in colour (from light orange-brown to dark blue-black)

Aspirin syrup + Iodine solution → No Change in colour (retains light orange - brown colour)

An aspirin tablet (acetylsalicylic acid, pKa = 3.49, molecular weight = 180.15) was taken orally with cold water to make a solution of aspirin in the stomach fluids of 0.00167 M. The cold water produced a temperature in the stomach temporarily of 25 °C. What is the percentage of aspirin in the ionized form in the stomach in which the pH of the fluid is 3.2?

If 1.2 g of aspirin were dissolved in 100 mL of water, how much aspirin might you be able to recover if you were to extract the aqueous solution with 100 mL of dichloromethane? Also calculate the percent recovery. If instead of extracing the aqueous layer with 100 mL of dichloromethane, what would have been teh percent recovery if you had used two sucessive 50 mL protions of dichloromethane?

FLUORIMETER LAB: A 0.1019 g portion of an aspirin tablet was dissolved in sufficient water to prepare 1.000 L of solution. A pipet was used to transfer 10.00 mL of the solution to a 100.00 mL volumetric flask. A 2.00 mL portion of 4 M NaOH (aq) was added to the flask, and the resulting solution was diluted to the mark with water. The fluorescence of the diluted sample solution was found, by the working curve method, to correspond to...
