Okay, I did a lab in class, but I'm having a little trouble with answering the questions about the lab... so your help would be much appreciated.
Okay, so first I added NH4OH, AgNO3 and glucose to a test tube.I saw that silver was coating the inside of the test tube, but the question is:
1. *Explain how the presence of glucose allowed this coating to form*
I thought the reaction of NH4OH and AgNo3, would produce NH4NO3 and AgNo3 (a precipitate), but apparently ther's more to it. I just really don't know where to add the C6H12O6 into the equasion. I don't need the equasion, I just need to understand what glucose has to do with it.
And I also have another question....
I added 5ml of Benedict's solution (it detects reducing sugars such as glucose and fructose) to 5 test tubes. THen to each of those 5 test tubes I added 8 drops of 2% glucose solution. I then heated the mixtures for ...
