  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.

  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.
