Repeat this titration at least three times. Results should agree to 0.1 mL. 4. Titration of juice samples. Add 25.0 mL of your beverage sample into a 125 mL Erlenmeyer flask. Repeat the iodimetric titration until you have three good measurements (again to 0.1 mL). Use the Q-test to check for bad data. 5. Titration of Real Lemon. Add 10.0 mL of Real Lemon into a 125 mL Erlenmeyer flask. Repeat the iodimetric titration until you have three good measurements (again to 0.1 mL).
