Quantifying the amount of glucose in a potato

  1. 1. Quantifying the Amount of Glucose in a Potato<br />Beryllium<br />JOSE, Williard<br />DAROYA, Rangel<br />UTANES, Kerwin<br />ELATICO, Adam<br />TANCHULING, Diego<br />MAGNO, Gian<br />
  2. 2. Intorduction<br />There are a lot of ways to determine the glucose concentration of a solution…<br />These include the use of special indicators, titration, or osmosis<br />But for this particular experiment, a different protocol has been used. <br />

  10. 10. Glucose and Potato Solutions<br />Five milliliters of sulfric acid was added using syringe<br />After adding sulfuric acid, two milliliters of potassium permanganate was added (syringe)<br />Time was recorded right after potassium permanganate was added until color disappears from solution <br />
