WebSo, vitamin C is oxidized by DCP in a 2 e{/2 H+ transfer. Figure 1 Redox titration with DCP provides a quantitative measure of the vitamin C content in a sample. The solution stays colorless until all the ascorbic acid has been oxidized. After this point, further addition of DCP will turn the solution pink. WebExperiment 31: Oxidation Reduction Titration of Vitamin-C (This experiment is from Santa Monica College.) Purpose • To standardize a KIO 3 solution using a redox titration. • To analyze a commercial product for vitamin-C content via titration. Background The two reactions below occur in the same solution. We will use these reactions in this Webare ready to titrate. Part A: Analysis of Pure Vitamin C Fill a buret with the NaOH solution that is provided. Weigh about 150 mg of pure vitamin C and record the exact mass. Work quickly, vitamin C is light- and air-sensitive. Recap the container immediately. Transfer the acid to your flask and add about 50 mL of water to dissolve it. 2t能存多少数据
