(a) The optical rotation [a] of aqueous samples of pure a-D-glucose D and pure ß-D-glucose were measured over time and a graph plotted (below). The optical rotation of both samples tends towards the same value, +52.7, as time proceeds. Explain, with the use of a diagram, why this trend is observed. +112 [x] +52.7 +19 Time
