1. a) As far as changes in optical activity go, was there any qualitative difference between the mutarotation of glucose and the hydrolysis of sucrose that you observed? Explain

b) Why does the sign of rotation change as the hydrolysis of sucrose proceeds?

c) How could you show, in principle, that the rotation that occurs in the hydrolysis of sucrose is due to hydrolysis and not just mutarotation? Describe some experimental tests that could be done.

d) In the mutarotation of glucose, 2ml of 6M HCl is added to speed up the mutarotation. Why is it not necessary to take the change in volume of the solution into account?
