Chem 14CL Summer 2008 Post-lab Report Guideline for the Vitamin C Analysis Experiment This is an individual report (I) ABSTRACT – Summarize the goal(s) and technique(s) for the experiment plus a summary of your experimental result(s). (II) DATA AND OBSERVATIONS Organize all your data and observations in a tabulated format for the standardization of sodium thiosulfate and the analysis of vitamin C. Your data should include the weights of various solid reagents and/or chemicals; all the volumes for the titrations as well as the color of the solutions before and after the addition of the starch. (III) DATA ANALYSIS (SHOW ALL YOUR WORK AND REASONING) Period 1 – Standardization of the Sodium Thiosulfate Solution (i) Calculate the molar concentration of the standard KIO 3 solution (ii) Using the initial volume and the end point volume, calculate the molar concentration of Na 2 S 2 O 3 for each trial of the standardization (iii) Calculate the average molar concentration of Na 2 S 2 O 3 solution
