The sensitivity of the Benedict's Test-Investigation Aim In this investigation, we will be attempting to find the lowest concentration of glucose that Benedict's can detect. Prediction I predict that that the 10% glucose solution will have the darkest colour dark after testing for reducing sugars whereas the 0.001% glucose solution will have the lightest colour. This is because as the percentage of glucose is increased the darker the colour will become meaning that there is more glucose present. I have predicted this after finding out some information about the Benedict's test. The Benedict's solution contains a weak solution of copper II sulphate. Reducing sugars can reduce this to a precipitate of brick red copper I oxide.
