The values of the specific rotation alpha20d for the alpha, Ask an Expert

Academics

The values of the specific rotation, [alpha]20D, for the alpha and beta anomers of D-galactose are 150.7 and 52.8 degrees, respectively. A mixture that is 20% of alpha-D-galactose and 80% beta-D-galactose is dissolved in water at 20 degrees C.

a)What is its initial specific rotation?

b) After several hours the specific rotation of this mixture has reached an equilibrium value of 80.2 degrees. What is its anomeric composition?

Would you please explain how to do both parts?
