ame ed 312 EXPERIMENT 21 Petry of Super ANALYSIS C. Determination of Optical Activities for Glucose, Fructose and Sucrose Copy the optical activities from your Datasheet into the table below: ANALYSIS Glucose Fructose Optical Activity A (enter for each sugar) +52.7 -92.4 Sucrose +66.37 D. The Composition of Sucrose Use Equation (21-2) to predict the optical rotation of a pure sucrose solution at the concentration of sucrose you prepared in the acid (from the left-hand table above) Predicted optical rotation for pure sucrose at this concentration Use Equation (21-3) to predict the optical rotation of the glucose/fructose mixture you prepared (right-hand table above). Predicted Optical Rotation: Assume that the sucrose decomposed into glucose and fructose in the acid solution. Use Equation (21-2) to predict the value of the optical rotation of the solution. Hint: In a 20.0 g sample of sucrose, half of the mass is glucose and half of the mess is fructose. Predicted Optical Rotation:
