Experiment: Quantative analysis of glucose using a colorimeter Apparatus 6 concentrations of glucose Test tubes Test tube racks Couvettes Water bath Colorimeter Syringe Risk assessment Lab coat because using Benedicts solution = corrosive Safety glasses because using Benedicts = corrosive Hair tyed back out of the way Bags under the desk out of the way Method There are six concentrations of glucose solution: 0.01%, 0.05%, 0.1%, 0.25%, 0.3% and x. The aim is to find the concentration of x. A control is also to be completed. A control is a sample used to compare the results collected. To do the control, the same volumes are used as in the other samples: 2cm3; 1cm3 of Benedicts solution and 1cm3 of distilled water. The other 6 concentrations were then mixed with Benedicts solution, each to the ratio 1cm3:1cm3 of Benedicts:glucose solution. Label each test tube with the concentration of glucose and then place them in the test tube rack. Once all 7 samples are complete, place them in...
