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 Solution 2.
Calculate the expected concentration (in mM) of ascorbic acid in Solution 2.

A 1000mg vitamin C tablet was finely crushed and transferred to a beaker where it was diluted with 100ml of water. This solution was heated for a period of time before being filtrated. The filtrate was transferred to a 250ml volumetric flask where it was diluted to the appropriate mark. 25ml of that solution was pipetted out of the volumetric flask and added to a 250ml flask. 5ml of KI, 2.5ml of HCl and 1ml of starch indicator solution was...

Calculate the weight percent of ascorbic acid in a tablet of Vitamin C from the following data: A 100 mg sample of a crushed Vitamin C tablet was dissolved in 40 mL of H2SO4 and 20 mL of water. Two grams of KI and 35 mL of 0.0107 M KIO3 solution was added, and the mixture titrated to a starch endpoint. The titration required 12 mL of 0.0790 M thiosulfate solution.

A student is given an antacid tablet that weighed 5.6832 g. The tablet was crushed and 4.3628 g of he antacid was added to 200 mL fo simulated stomah acid. This was allowed to react and the filtered. It was found that 25 mL fo this partially neutralized stomach acid required 8.5 mL of a NaOH solution to titrate it to a methyl red endpoint. If it took 25.5 mL of this NaOH solution to neutralize 25 mL of the...
