Analysis of Commercial Vitamin C Tablets. (Ascorbic acid content in one tablet)

Date: 25 Nov, 2004
Objective:
1. To standardize sodium thiosulphate for titration use.
2. To find out the concentration of Vitamin C in the tablet.
Theory:
This experiment involves titration of redox reaction. Redox reaction means reduction and oxidation. In which oxidizing agent and reducing agent are mixed and oxidize/reduce each other. One losses electron(s) and increase in oxidation number when is oxidized, and vice versa.
In order to find out concentration of the ascorbic acid in the tablet, a redox reaction of it with iodine was done. While iodine is an oxidizing agent and asco…
