NaOH Standardization and Titration of an Unknown Organic Acid Overview: Methods for counting the number of molecules in a sample is a major emphasis of laboratory work. In this experiment we will use the method of titration to count the number of acid molecules in a solution. Measuring mass is a relatively easy procedure to do in the lab (although a balance is expensive). Counting the number of particles requires more effort. Molecular counting can be done by setting an unknown amount of a substance

Laboratory Report: Experiment 3 Analysis of commercial vitamin C tablets Name: Cheung Chun Hin‚ Harry Class: 6L (12) Date: 14-10-2009 Objective: To determine the content of vitamin C in commercial tablets (redox titration and back titration) Principle of method: Vitamin C‚ which is ascorbic acid‚ reacts with iodine rapidly in an acidic medium. C6H8O6 (aq) + I2 (aq) C6H6O6 (aq) + 2H+(aq) + 2I- (aq) Since iodine dissolves slightly in water‚ ascorbic acid cannot be titrated
