Unformatted text preview: It took about the same amount of KIO3 to titrate the ascorbic acid as before and we had same initial mass as we did experimental mass. Therefore our conclusion was that heating the ascorbic acid had no effect on the mass of the ascorbic acid. Part 3: Analysis of Vitamin C Tablets In Part 3 of this experiment we were to dissolve vitamin c tablets in water and then titrate them just like the others. The only difference in this experiment and the previous two is that we were to find the percent of the tablet that was actually vitamin c. The initial mass of our tablet was .61 g and it only took 10 mL to titrate the solution. The final experimental mass of the vitamin c tablet was .528 g. This means that the percent of the tablet that was vitamin c was 86.6%. ERROR The errors that we encountered in this experiment were nonexistent....
