A 100 mg vitamin C tablet weighed 1.573 g. A student crushed the tablet and transferred 0.117 g of the crushed powder into a 100 mL volumetric flask, dissolved the powder in ~30 mL DI water, then filled the flask to the calibration line with DI water and mixed well to create Solution 1. The student then transferred 22.1 mL of Solution 1 into a 100 mL volumetric flask and diluted to the calibration line with DI water to create...

II. Digestion of Acetylsalicylic acid(standard and tablet) with NaOH . Digestion of Acetylsalicylic Acid Standard to Prepare Stock Solution: Obtain ca. 0.1 g dried acetylsalicylic acid (MM = 180.16 g/mol), accurately weighed, and quantitatively transfer to a 125-ml Erlenmeyer flask. Add 5 ml 1.0 M NaOH and heat mixture to boiling on a hot plate. This will hydrolyze the acetylsalicylic acid to sodium salicylate. If necessary, rinse down the walls of the Erlenmeyer with DI water to ensure complete hydrolysis...

Aspirin is acetylsalicylic
acid (ASA) (
C9H8O4). It reacts with NaOH ( a
base) to produce salt (sodium acetylate) and water. Both Aspirin
and NaOH react in 1:1 molar ratio, as
C9H8O4
+
NaOH →
NaC9H7O4
+ H2O
So, moles of NaOH = moles of ASA
Or, mmol of of NaOH = mmole of
ASA
