Explain the rotation of the solution increases overtime

Reference no: EM13653630

Polarized light passing though a sugar solution is rotated. A polarimeter allows us to measure the size and direction of the rotation. A freshly prepared solution of alpha-D-glucose shows a specific rotation of +112 degrees. Overtime the rotation of the solution decreases and reaches an equilibrium of specific rotation of +52.5 degrees. In contrast, a freshly prepared solution of beta-D-glucose shows a specific rotation of +19 degrees. The rotation of this solution increases overtime to +52.5 degrees. Calculate the percentage of the two forms of D-glucose at equilibrium.
