- Read the Limit Test for salicylic acid in aspirin below then answer the question below. Remember: Aspirin = acetyl salicylic acid (ASA), and salicylic acid = SA Limit Test for salicylic acid: Extract powdered Aspirin tablets (i.e., active + excipient) containing 0.4g acetylsalicylic acid (i.e., active) with 4 mL of 95% ethanol. Add water to give a final volume of 100.0 mL and mix. Transfer 50.0 mL of the filtrate to a Nessler Cylinder and add 1.0 mL of acidified ferric ammonium sulfate solution. Mix and allow to stand. Prepare the standard solution used for comparison as follows: To another Nessler Cylinder add 3.0 mL of freshly prepared 0.01% (wt/vol) salicylic acid, 2.0 mL of ethanol, 1.0 mL of acidified ferric ammonium sulfate solution and sufficient water to give a total volume of 51.0 mL. Mix. A violet colour produced by the sample should not be more intense than that of the standard, used for comparison. Example of "Limit" calculations: Based on the above limit test, the…Actual volume of water delivered by pipet and Percent error in volumetric pipetTo prepare the solution you would place the solute in a 50.0 ml volumetric flask, and then fill to the mark with water while mixing.
