  3. What is the chemical formula, chemical structure? • Chemical formula – C6H8O6

  4. Molar Mass & CAS Registry # • Molar mass- 176.14 g/mol • CAS # - 50-81-7

  5. Health Benefits… • Vitamin C is needed to make collagen which is important for the skin, the gums, the teeth, blood vessels, bone ligaments and tendons. • It’s a powerful antioxidant. It also helps prevent chronic degenerative disease.

  8. juices... Allen’s Fruit Punch Orange Vitamin Water Minute Maid Odwalla Mango Juice No name apple juice

  9. What do you do? • Measure out 100 ml of the juice in a flask. • Use the micropipette to measure out 2ml of the starch indicator which we added to the juice.

  10. Next • We put a 50/50 diluted potassium iodide solution in a burette. • We slowly added this to the juice sample until there was a noticeable short lasting change in the color. • We calculated how much potassium iodide solution it took to change the color of the sample.

  11. Skills… • Materials: Burette and a pipette, micro pipette. • Starch indicator that tells when the reaction is done, it will change color.

  12. Techniques… • Techniques- titration is when you add a substance to the substance that you're working with and it will react with the amount. It will show how much is there. • Pipetting- you draw an exact amount of the substance into the pipette.
