Biology help - distinguishing between very concentrated samples Watch
'why it is not possible to distinguish between very concentrated samples, even when their concentrations are different.'
I've probably missed something quite simple but I've been stuck on this question for a while so thought I would reach out for some help.
Context: this is for the Benedict's test for sugar
If the samples are highly concentrated with reducing sugars, both solutions will be a red colour when mixed with benedict's solution. This means that despite the concentrations being different, they will be impossible (or very hard) to distinguish as they are both the same colour.
