Determination of Vitamin C by an Iodometric Titration Purpose: The goal of this lab is to determine the concentration of vitamin C in juices and Real Lemon. A redox titration, involving an iodometric method, will be used to do the analysis. The samples will be classified by their Vitamin C content. Introduction: Although most mammals can synthesize vitamin C, or ascorbic acid (C6H8O6), from sugars, man must ingest considerable quantities of this substance. …showed first 75 words of 550 total…

Add 25.0 mL of your beverage sample into a 125 mL Erlenmeyer flask. Repeat the iodimetric titration until you have three good measurements (again to 0.1 mL). Use the Q-test to check for bad data. 5. Titration of Real Lemon. Add 10.0 mL of Real Lemon into a 125 mL Erlenmeyer flask. Repeat the iodimetric titration until you have three good measurements (again to 0.1 mL).
