A 5.500g mixture of sodium chloride, silicon dioxide, and ammonium chloride wasn’t heated by in order to sublime off the NH4Cl. After heating to remove the NH4Cl, the student reported the sample weighed 4.310g. If the original mixture contained 22.0% ammonium chloride, was all the NH4Cl removed or driven off by heating. Document answer.

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…
