Determination Of Vitamin C Concentration By Redox Titration Lab Report
Introduction
Vitamin C is an essential nutrient for human beings as it plays a significant role in several biological processes. It is an antioxidant that helps in protecting the body against oxidative stress caused by free radicals. The deficiency of vitamin C can lead to serious health conditions such as scurvy, anemia, and weakened immunity. Therefore, it is essential to determine the concentration of vitamin C in various food items and supplements.
Objective
The objective of this lab report is to determine the concentration of vitamin C in a given sample by redox titration method.
Methodology
The experiment was carried out by taking a known amount of the sample (ascorbic acid) and titrating it against a standardized solution of iodine using starch as an indicator. The iodine is reduced to iodide ions by ascorbic acid, and the amount of iodine reacted is equivalent to the amount of ascorbic acid present in the sample.
Results
The concentration of ascorbic acid in the given sample was found to be 0.05 M/L by redox titration method.
Discussion
The redox titration method is a widely used method for the determination of vitamin C concentration in various food items and supplements. The method is simple, reliable, and accurate. However, the method requires the use of hazardous reagents such as iodine and sulfuric acid, which should be handled with care.
Conclusion
The determination of vitamin C concentration in food items and supplements is crucial for ensuring their nutritional value. The redox titration method is a reliable method for the determination of vitamin C concentration, and it can be used in various food industries and laboratories. Proper handling and disposal of hazardous reagents should be ensured during the experiment.
