4. A student dissolves a-D-glucose in solution. What sugar molecule(s) is/are present after the solution reaches equilibrium? Use structures to explain your answer. 3 marks
Polarized light passing through 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 the same value as that...

what mass of sugar would have to be dissolved in 60g of water to yield a 25% solution ?
Sucrose, a sugar, decomposes in acidic solution to produce glucose and fructose. The reaction is first order in sucrose, and at 25 °C the rate constant is k = 3.60 x 10-3-1. If the initial concentration of sucrose is 0.050 M, what is the concentration after 2 days? O 0.042M 4.3 x 10-3M O 0.028 M 0.013 M
