Question-Why would it be important to place the same amount of a solution in the polarimeter tube when measuring optical rotation as the amount of solvent when measuring the blank?
a. So the density of the blank can be added to that of the solution when calculating optical rotation.
b. Biot?s law, used to calculate optical rotation, requires that the volume of the blank be subtracted from that of the solution to arrive at a proper density value.
c. None of the answers shown are correct.
d. Only a certain volume of liquid can be placed in a polarimeter tube.
e. So the path length can be easily converted to mL's when calculating optical rotation
