Answer:
The test for a reducing sugar using benedicts solution is by, first making a colour chart, using various KNOWN concentrations of glucose situations, if available.
Then use the unknown substance and add benedicts solution and boil, a red precipitate should appear and the "redder" it is, the stronger the concentration.
You can then filter off the precipitate and place the remaining liquid into a cuvette and pass through a colorimeter, on a red filter, the more light that passes through, the sronger the concentration. Compare this solution to your colour chart to help you determine the concentration of the reducing sugar.
