    All of my results for the task "determining glucose concentration (using a colorimeter") were anomalous/ none of them made a pattern! Has anyone done the experiment, and if yes- please share your results!
    I used 1%, 0.5%, 0.25%, 0.13%, 0.06% and 0.00% (control) glucose for the experiment.

    🙋🏻 I did
    Our results were blue for all ( different shades though) but two that were brick red. Are you sure you left them in the water bath for a good 15 mins at 80'C and added the right amount of Benedict's solution (should be 10Cm^3) and then for each test tube take out 1cm^3 of the combined distilled water and glucose?

    All of the results came out well, it was just an issue with the colorimeter that ruined the results
