Question 1

A solution is prepared consisting of glucose, hydroxide ion and a dye and placed in a flask which is immediately stoppered trapping an air space. The following observations are made. (Note: we are trying to figure out what is going on in this reaction from the given information. There are three questions.)

The conclusion that can be made from this statement is:

Reason for Answer:

Question 2
