I am confused with benedict test.
I want to know will a glucose solution with a very low concentration ever turn the solution+ benedict solution to brick red , or the solution stays whatever colour it has reached even if we heat it for a longer time
And my other doubt is when testing to find the concentration of glucose solutions for how long should we heat the solutions, I know that the time should stay constant, my question is if we keep heating the solutions for a long time will all the solutions eventually change to brick red?

Technically, the color of the solution, will correspond to the concentration of the reducing sugar present in the Original solution. Heating it for a longer time will not be sufficient to change your results.

you should heat the solution for 2 minutes and then record your observations and then replace the samples in the water bath for a further 2 minutes (4 mins incubation time ) and then remove them from the water bath and record your results
