Activities
01) Sugar Concentration through Polarimetry
Students use a polarimeter to determine the unknown concentration of a sucrose solution.
02) Specific Rotation of Sugar
Students use a polarimeter to experimentally determine the specific rotation of the sucrose molecule.
03) Kinetics of Sugar Rotation
Students use a polarimeter determine reaction order and rate constant of an acid-catalyzed sucrose hydrolysis reaction and an invertase-catalyzed reaction.
04) Sugar Concentration through Polarimetry: Biot's Law
Students use a polarimeter and Biot's law to determine the unknown concentration of several sucrose solutions.
05) Equilibrium of Sugar Mutarotation
Students use a polarimeter to determine the α- and β-anomer concentrations of a D-glucose solution at equilibrium, and calculate the equilibrium constant.
