This document summarizes an experiment determining vitamin solubility and content. Vitamins were tested for solubility in water and methylene chloride to classify them as water-soluble or fat-soluble. Vitamin C content was measured in fruit juices through redox titration with iodine. Heating a sample for 10 minutes destroyed over 90% of its vitamin C content, demonstrating vitamin C's instability to heat. The experiment showed the difference between water-soluble and fat-soluble vitamins and importance of vitamin C for nutrition and disease prevention.
