Prediction: In the first part of the experiment (simple Benedict's test), I predict that out of the three solution samples; glucose, sucrose and sample X, only glucose will change from the blue colour. I do not know what the substance in sample X is and therefore cannot comment on the outcome. However in my opinion sucrose will not change colour during this part of the experiment. In the second part of the experiment, when using acid to break any glycosidic bonds and sodium hydrogen carbonate to neutralise the solution, I predict that sucrose will change colour. In my opinion the part of the experiment will make no difference to the glucose and therefore...
