WebIn this two-part video, we look at how to use the Benedict’s test and a colorimeter to quantify the concentration of glucose in a solution. First I take you through the science behind the Benedict’s test and discuss why the colour of Benedict’s reagent changes when it reacts with glucose. I then explain how a colorimeter works and how we ... WebTo convert colorimeter absorbance readings to concentration, you need to make up some standard solutions of starch, add a fixed volume of iodine solution, and take colorimeter readings. Plotting the colorimeter readings against concentration gives you a curve.
