25. Solving a chemistry problem
6. Give a definition of the concept “Specific rotation”. Write the formula for scopolamine hydrobromide. Calculate the specific rotation (in terms of dry matter) if the angle of rotation of a 5% aqueous solution under standard conditions (200 C) in a 20 cm long cuvette is -2.190. The weight loss upon drying is 11.6%. Evaluate the obtained value in accordance with the requirements of the Global Fund (-22О -26О). List the factors influencing the value of specific rotation.
