1. Calculate the average volume of iodine solution used from your concordant titres.
2. Calculate the moles of iodine reacting.
3. Using the equation of the titration (below), determine the number of moles of ascorbic acid reacting. Ascorbic acid + I2 → 2 I- + dehydroascorbic acid.
4. Draw the chemical equation of Ascorbic acid + I2 → 2 I- + dehydroascorbic acid.
5. Calculate the concentration in mol/L of ascorbic acid in the solution obtained from all of the samples. Also, calculate the concentration in mg/100mL or mg/100g of ascorbic acid in all of the samples.
