1.Using a plastic syringe, introduce 10cm cubed glucose solution and 5 cm cubed sulfuric acid into a flat-bottomed tube. Draw 2cm cubed potassium permanganate solution into a syringe, and press the stop-watch at the moment this addition is made to the contents of the tube. Record the time (secs) for complete decolorization. 2.Using the syringes, make dilutions of the glucose solution provided to obtain solutions containing 9, 8, 7, 6, 5, 4, 3, 2, and 1g glucose per 100 cm cubed distilled water. 3.Repeat procedure 1 with each glucose solution. Record all results in a table, and plot your result in graph form. 4.Use the graph to estimate the concentration of glucose in the unknown solutions.
Standard solution: 10g glucose in 100 cm cubed water
•15 flat –bottomed tubes
•60 cm cubed glucose solution
•30 cm cubed 0.01 M potassium permanganate solution
•3*10cm cubed plastic syringes
•60 cm cubed 1M sulfuric acid
•150 cm cubed distilled water
The data that I have used does support the hypothesis, and the results have been put in order and labeled. You find that in my line graph the glucose percentage seems to go up in a non-straight line form and as soon as it reached near about 7:40 between 2% and 1% it rapidly decreases in minutes down to about 3:00. To me the reason why it went up so...
