I've never done an experiment before. So, the methodology provided in this pdf is quite confusing. Link to the pdf: https://www.canterbury.ac.nz/media/documents/science-outreach/vitaminc_iodine.pdf
So, this pdf here details the methodology for conducting an iodometric titration to find ascorbic acid content in fruits/vegetables. On page 2 under "Method" section, its written how to make a 100 ml of sample solution with 100 g of the vegetable.
But in the titration experiment, we use only 20 ml of this sample solution. If we're taking only 20 ml for titration, wouldn't the tested ascorbic acid content be low? I mean, if you tested only 20 ml of the sample solution, then how is it representative of the amount of ascorbic acid in 100 g of that vegetable?
