Transcript

  • 1. Quantifying the Amount of Glucose in a Potato
    Beryllium
    JOSE, Williard
    DAROYA, Rangel
    UTANES, Kerwin
    ELATICO, Adam
    TANCHULING, Diego
    MAGNO, Gian
  • 2. Intorduction
    There are a lot of ways to determine the glucose concentration of a solution…
    These include the use of special indicators, titration, or osmosis
    But for this particular experiment, a different protocol has been used.
  • 3. HOW DID WE DO IT??!! :O :O :O
  • 4. Preparation of Solutions
    100mL of 1 M of sulfuric acid
    125 mL of 0.0025316 M of Potassium permanganate
    Glucose solution (1%, 2%, 4%, 8%)
    Potato Solution (approximately 0.5 g of crushed potato in 50mL of water)
  • 5. Preparation of Solutions
    Fig 1. Adding sulfuric acid in distilled water.
    Fig 2. Stirred potassium permanganate in distilled water.
  • 6. Preparation of Solutions
    Fig 3. Weighing of solid glucose to be used in solutions
    Fig 4. Adding distilled water to solid glucose.
  • 7. Preparation of Solutions
    Fig 5. Weighing of potato slices.
    Fig 6. Three of approximately 0.5 grams of potato slices.
  • 8. Preparation of Solutions
    Fig 7. Crushing 0.5 grams of potato slice using mortar and pestle.
    Fig 8. Placing crushed potato in Erlenmeyer flask.
  • 9. Preparation of Solutions
    Fig 10. Three potato solutions, four glucose solutions, and a potassium permanganate solution
    Fig 9. Adding distilled water to crushed potato.
  • 10. Glucose and Potato Solutions
    Five milliliters of sulfric acid was added using syringe
    After adding sulfuric acid, two milliliters of potassium permanganate was added (syringe)
    Time was recorded right after potassium permanganate was added until color disappears from solution
  • 11. Adding Sulfuric Acid
    Fig 11. Adding sulfuric acid to glucose solution.
    Fig 12. Adding sulfuric acid to potato solution.
  • 12. Adding Potassium Permanganate
    Fig 13. Adding potassium permanganate in glucose solution while timing.
  • 13. RESULTS!!!!
  • 14. Results
    The following slide shows the reaction times taken by the solutions:
  • 15. Results
  • 16. Discussion
