analytical sample solution. What is the value for the precise mass in mg of the Vitamin C
tablet that was dissolved in your analytical sample solution?
In the analysis of the ascorbic acid content in a Vitamin C tablet, we must examine each
of the three acceptable trials. Your titration volumes of the NBS solution should be
approximately 10-20 mL. For each trial, what is the precise volume in milliliters of NBS
used in the titration of the 10.00 mL Vitamin C sample(e.g. 10.45mL)? 79 Using the volumes of NBS solution you just entered and the average molarity of the NBS
standard solution, calculate the milligrams of ascorbic acid in the 10.00 mL Vitamin C
sample for each trial. What is your calculated milligrams of ascorbic acid in the 10.00
mL Vitamin C sample, for each trial?
Using the milligrams of ascorbic acid you entered above, the ratio of total sample volume
to aliquot volume, and the total milligrams of the Vitamin C tablet that you dissolved,
calculate the mass of ascorbic acid in the Vitamin C...
