Record the light intensity and color of solution at even angle increments through .
The Polarimeter can be used to measure chiral properties of optically active samples without chemically modifying or destroying the sample. This is a vertical polarimeter that uses a 589 nm LED, a fixed polarizer, and a manually rotated polarizer to detect changes in rotation of plane-polarized light in the presence of an optically active compound.There are important factors affecting the outcome of the experiment. Optical rotation depends on the number of molecules encountered by the light during the experiment. Two factors can be controlled in the experiment and must be accounted for when comparing an experimental result to a reported value.Experiment #6 from Organic Chemistry with Vernier.
